The Bibites
A downloadable project for Windows, macOS, and Linux
The Bibites is now available on Steam if you would prefer to download there. Its the same version with the added benefit of steam integration, community file sharing and automatic version updates.
Welcome Everyone!
This is The Bibites
A simulation where you are able to watch evolution happen before your very eyes!
Each bibite (the small critters you see on the screen) starts off with an empty brain (they do nothing) and pretty basic genes (they all look alike).
Through random mutations, one can be spawned with a brain connection that will link two neurons and might trigger a behavior, like going forward, which will allow them to eat food, and then reproduce with the energy gained.
You have reproduction, mutations, and natural selection, which leads to ...

With time, this develops into complex behaviors, like following pheromone trails to hunt other bibites, or stockpiling food in a specific area of the map.
Present Features
- Vision
- Procedural Sprites (generating a custom sprite for each bibite from their genes)
- Self-awareness (state, health, energy, etc.)
- Pheromones (producing and sensing)
- Grabbing and Throwing stuff (pellets and other bibites)
- Materials and Digestion Simulation
- Realistic Energy System
- Neural Network Brains
- Internal organs and genetically weighted apportionment
- Speciation and lineage trees
- Statistics and graphs for analysis
- Engineering Tools to create your own bibites and scenarios
- Challenges to test your genetic / brain engineering skills


The simulation is also interactive, allowing you to YEET bibites and pellets around. You can selectively kill bibites, feed them, force the laying of eggs, and so much more.
It's also highly customizable, allowing you to test a nearly infinite number of scenarios. How will they evolve if there is no drag (no friction)? What about if moving is extremely energy-costly?
It's your job to test it all, I sure can't do it by myself.
Planned features
- Seasons/cycles/events
- DOTS based parallel computing structure (greatly improved performance)
- Sex! (Sexual reproduction, polymorphism, castes, etc.)
- Module-based systems for unbounded evolution and incredible performance
- Biomes (environmental simulation)
- Evolving ecosystems (the plants/food evolve too)
- Rocks (Movable objects)
- And much more!
THIS IS THE STANDARD AND COMPLETE VERSION OF THE GAME and will continue to be updated and supported FOR FREE with all the features of the game besides the ones specific to Steam such as Steam achievements, the Workshop, and leaderboards.
Linux Users:
There seems to be an issue with some Linux users. If the game displays issues, add the "-force-vulkan" command line parameter when launching the game.
Mac Users:
Apple needs you to run any app from the Application folder. So make sure that's where you extract the .app folder.

Been looking for an app like this since the days of Artificial Life Lab for PC decades ago. Finally, an intellectually stimulating app on Steam. I also downloaded from this site so no Steam required.
really fun game but there isnt really much evolution except for the colour of the bibites
lot more than that
Idea: multiple resources that a bibite needs to reproduce to make for more types of environments
like what
Water or more types of food, like different nutrients
there's no male or female, all bibites are acexual
asexual means you aren't attracted to anyone, not gender. i think the term you're looking for is agender ^w^
though that still wouldn't be the correct term for bibites specifically. since they lay eggs, and don't mate with other bibites (for now), that would mean that they are parthenogenetic females! ^w^
um do what you want to do add a cocking thing or bildings (more) or let us control a bibibte
and the ditet 0 best for plants 0.25 best for fungi 0.5 best for eggs 0.75 best for larvae 1 best for meat larvae are what comes out of a egg and becomes a adult day and nehit vejen is /2 in the nheit day is normal it is a gradual change does other things too add fish simmer to maet diet 0.87 look in the reedit for more tag fitecher rucwest
other changes add mimeres and pozen look at the reedit some peeps have good ideas and change to what you like PS raspberry pi download in 0.6.3 pelz or make it a septet update ok? y/n
the other changes in 0.6.4 or another one like 0.8 0.7.8 0.7.4

sims:moon and mars (whit craters)
intrnel organ damidj
ps:a mod that makes a report every 1h-1d cold be good for test sims like _yemm_'s hazard (3 new hazeds 1 posings 2 free hp 1/4 grofe 3 brayk gane hp fuse lose hp i have a idea for a engey one too)
oh and mayby runing the trnment maps? ...we need a new download it is linux armor cpu and if you ruply to this i'l my idea for a new noad tipey self-destruct for midt tick noads after a crti number of pulses it dsapers sorry for speling
the flower is from plant daddy and if you need help wihe gpu ask kodub bcosas he is the maker of dustsim
bibites thirst so to do this we need 2-3 new pellet tips 1 water it appears in "lasck" around the map darker=more water water mantanes water amout at 0% -pers hp 25% bar red 50% bar yellow 100% bar green (this is the thest bar) 2 pee more=liter water is used makeing it now bibites do not need a abotecl flued BUT we cold store pee in the egg organ (as a substast it is a pellet outside) oh and bibites who have a good immune system can drink it 3 milk taeks water to maek it is good for littal bibites the pellits also get bigger/smaller
summery the pellets need a evaporation system (all back to water!)(and rain) they all can have minerals/salts in them for now the only solid is ice and milk cold be stored in a "udder" and new genes
eggeaters:1 more pellet and more geans1 yolk comes from braking eggs it is yellowy and we will need longer hatch time for a nech.
fish as a food sorse now these fish are pellets in 2+at 1 they are a bibite looking thing all fish are deep blew and here it's bibites>fish>planten and fish herding gean at 1
Hi
i am linux mint user and vanna play this game. But when i run
TheBibites.x86_64 or TheBibites_s.debug, the terminal says:
"FindDataPath: Player data not found!"
What it can be?
And how can i fix it?
Hey. I had a situation in this game where I had a lot of hours in one of the simulations and a lot of species but suddenly they merged into one species that was once the first but died out and now each of the creatures was that species and it's not like they became similar because they were very separate from it and I don't know what to do, I tried to go to the previous save but it reappeared after the same time.
I'm on Linux, and I'm incapable of editing simulation speed. 0.5x gives the same speed as 100x. 1 second in game passes in multiple real minutes, and I can't change it.
It might take too much processing for your device to go any faster
if there are updates to the game will i have to manually update the game or will it just...update by its own? just curious.
if you want auto update get the steam version, itchio doesnt have auto update
k
Are there any simulation differences between 6.0.1 and 6.1.1
yes
sometimes when I boot the game it will say 1x speed but they wont move even if I up the speed
Hi :) Why should I pay 10EUR on Steam if it's free here? I don't get it. What's the catch?
If you are able to support the project, buying on Steam is a way to do so. The two are the same. No catch :)
Some people prefer the installation/update management of Steam as well as the achievements and workshop integration.
Hey can you make a mobile port so the game is available for ppeople who don't own a pc still good though also YEET
yep or a raspberry pi
Getting error: "The bibite template 'Basic Bibite.bb8template' was not found in your template folder" on a new default simulation on a fresh install of The Bibites 0.6.1.1 linux (Fedora). Does this have something to do with the space in the filename? '-force-vulkan' didn't work.
Looking into this. Its been reported by a few linux users but we have yet to track which distros. In the meantime, you could try Wine or Proton to run window's version
I'm getting this issue on Zorin OS
What are the plans for this game, what can be done in the future? Has current artificial intelligence machine learning helped development?
You may be interested in our Trello for an idea of the projects road map.
We ironically have yet to use AI or ML tools in The Bibite's development
look at the comments
Will the game still be updated at ich.io? the steam version recently reached paid early access and here the last update we got is from october 2024...
It will be update here to 0.6.1 (same as steam) in a few days after early bugs on steam have been squashed and it is considered stable.
cannot move camera using the arrow keys, anyone with the same issue or resolution?
If its not on, arrow key control can be turned on in game settings. Moving forward (0.6.1) it will be enabled by default.
Oh and, I can't see ANY organ, i can only see its contents??![]()
Linux version may be improved with 0.6.1 release coming to itch.io in a few days. Let us know if there are still problems with Linux version then and we will try to address the issues.
Not to get anyone to do anything with this BUUUUT, you did infact ship the burst debug info... On linux specifically...
>Linux
>.zip
whyyyyyyy........
Is it not possible to unzip a file on Linux ?
You can, there's a command for it, "unzip"
...
I cannot move using wasd or arrow keys
noone said that was a thing in the first place
I mean move the camera, I found the settings but sometimes it breaks
This is a simulation of life, not a game like spore. You control the environment, not the creatures
You can move the camera with wasd
Same
You can enable in the game settings
Hi, I'm trying to run the game on Linux and I get this message "
A Problem Occurred
Load System
The bibite template Basic Bibite.bb8template was not found in your template folder.
". Does anyone know what's going on?I get the same error
when is 0.6.1 coming out
Check the Patreon
now
btw changing background color is broken.
I love this
i severely dislike how, when two bibites make contact, the defending bibite is just launched across the screen, ending all engagements as quickly as they began. i wouldn't consider this combat.
my dominant species in my world right now gets to around 30u with jaw/attack strength around 450/220N if that means anything.
also, if one bibite can comfortably fit through the other's throat WAG/bite size, they should just get nommed whole. this could open up for an internal parasite build or make bibites more likely to become predators, and give bibites a chance to escape if their attacker dies soon after.
I booted up a save from the 5.1 version in 6.0 and it seems none of the 5.1 Bibites are able to eat. The bite bar progresses, but they don't seem to be able to swallow.
no organs at time
tried to post a pic but it won’t let me. My lineage randomly went extinct and spawned in a new yet similar species to what I had saying the same generation, yet not having any parent species anymore which makes zero sense. Wouldn’t the simulation try to do the basic bibite again? Not to mention it’s next to impossible for my bibite to have gone extinct to begin with. There are random lines all over my tree and I can tell that the new species it spawned in. Is just a derivative of the first species, yet it says it’s connected in zero way whatsoever
also, zero hotkeys work and the only way I can zoom on the tree is to to transfer the file over to my laptop and use the touchscreen
wait my first comment miiight be because they reached 150%. It would do that yeah? Spawn a new tree once there’s truly a new species? Then they just outcompeted what made them making the first tree come to an end?
i would like an option to purge all pellets under a certain size to improve performance in one or two clicks.
You outta tweak the strengths. a micro creature should not be able to have 14000N of jaw strength
I would be very curious to see the genetic makeup of this bibite 🤔
sure, just over 250 hours long with these pics
yaay
help it doesn’t go past 50%? I’m on max and I think I did everything right (I’m not sure though)
I am assuming this is on Mac. Make sure to EXTRACT the files from the downloaded zip file into the application folder. Hope this helps.
I keep getting an issue where many food particles stack on top of each other in the center of my zone. It lags the simulation severely. Is there any way to fix this?
I love the new species tracker, but can it be possible to make it never delete a species record, i can't just go manually favorite every species when im running the simulation and doing other things.
You can lower the pruning threshold to 0, in the lineage panel settings. That would be similar to favoriting all the existing and future species
Eventually species will still disappear if they shrink to small enough numbers, that's just entropy and the log-like logic I implemented for compression!
I am on windows but when I try to launch the application but loading bar does not go past 50%. Any suggestions to get it to work?
Try running it as administrator. That's what worked for me.
incredible! i love the systems at play in this simulation , im about to run this on a high end gaming pc so i can really reap the benefits of such a complex system and im so glad your developing this even further! this may truly be the best simulation ever!
