Welcome to the Cattopia National Laboratory's Big Box Of Catto Research™, where you can play around with all sorts of elements in the form of little creatures known as Element Cattos and see how they interact in different conditions and environments. This fun and informative* exhibit is sure to provide hours* of fun for curious schoolchildren and adult nerds alike!*
*hopefully
*milliseconds if you choose to play with the more radioactive elements
*The CNL is not responsible for any damage, collateral or environmental, caused by experiments in the Box™, including the partial or total destruction of the space-time continuum
This game is a work in progress. Feel free to report any bugs or inaccuracies, or suggest features you'd like to see! I'll fix and add whatever I can in updates. Chemical reactions will be added in a later update; chemistry is very complex and we're still figuring out how to go about it in this game.

Made a mod with an updated port of the game: https://git.gay/mupsie/ecatto-decomp/releases
I’m lazy to make an itch page rn :b
I got a problem,for some reason on mobile the zoom and dragging are borked up
If you’re using the web version, its like that, don’t know how to fix it. If its the apk one, it works fine, atleast for me and the few other people who used my mod
I'm using the apk
I'm using the apk
rn im waiting for the mobile port to be updated or for an official mobile port
How do i get Positronium?
i got used to most of the cattos having white eyes that the banner now makes me confused
Haha 2 years
Life is CBAT
This is the cutest game I've ever seen, great work! Also very nice to have native linux support.
does the linux version use x64_86 or ARM
Please make a mobile version.
Someone made a mobile port, you can try that. But unless this game starts raking in a lot of money, I don't think it will be of priority
the game is just not opening for m
high speed photons colliding into sufficiently heavy element will crash the game, like, when you lower the time rate and throw the photon at the opaque walls, then if it collides with heavy enough catto will crash, i reckon its trying to summon too many objects(particles) at once
oh its any catto, i think its collision handling or something
would anyone believe me if i said a friend of mine drew some characters (im not kidding)
muonium stops blinking when theres 6 or more cattos in the scene, for some reason Bungy doesnt count
oh its any catto that counts towards as "cattos" reaches 6, all blinking stops except for Bungy and Purrcent
photons crash my game every time I use them in slow motion fyi
the AI limit has been raised to 29 it looks like, at 30 or higher they dont react to blackhole or hammer
small bug with photons. also just discovered it's more than just D that it happens to lol
video
in this case the "EEEE" joke works cause my CPU fan speed spikes
Depending on the x in the 1e-x the freeze lasts for different times. I think the catto is being flung far away? idk
ok yea i really gotta cap the cattos' speed lmao
This is my design for Element 1e19.
If you want to know what this is, Basically, The right ear is the exponent. (Potassium)/19) Next, the body, the head, and the left ear, are the base. (Neon/10) Then, the p, is the ^ in this case. And finally, the black rectangle is the sign that you might need to stop going so far.
how do I download it on IOS I can’t figure it out send help omg my 2$ ausnizysmaKgzbMKHNkau
https://unexian.itch.io/elementcattos-plus this is a mobile port
When's the Breaking Bad Crossover?
screen saver would be nice
You better explain bro
Ooh I'm telling
Uh can i explain again
Please let us slow down time
you can use cheat engine to slow down time with speedhack (it changes time speed)
good news! in the upcoming update, you're going to be able to slow down time!
Your prayers have been answered!
the autoclicker was a mistake the game runs at 5 fps now help
Maybe a community contribution board/service could have people suggest chemical bonds (maybe starting with 2 atom bonds) and have it so if multiple people agree that a chemical is accurate it will get added. Since this does not seem to be a program for scientific purposes, inaccuracies should not be a big deal with my current understanding of this project.
While it may be too complex currently, adding a system that handles chemical reactions + a library of every chemical reaction could allow people to update the chemical reactions without needing to redownload the game, also potentially allowing for a simple online program that checks a server for the latest version of the library upon startup.
I think I hit the upper limit
i dont even think this causes a black hole anymore lmao
You can turn off Endable world, though yes, this probably skips that and goes straight to the reset
Also I made bigger ones. Going to exactly the integer limit is hard
slightly bigger
Going exactly to the integer limit is simple, but excruciating.
actually, notably, the one at the integer limit still produces a black hole
Somehow got to a state where so many elements were exploding that it was more sounding like a chainsaw and I got a cutscene or smth. 10/10.
It's insane how this game blew up out of nowhere, since I have never heard of it beforehand
I watched a video about it
fun
please make a mobile app
^.u.^
i did ^w^
oh ma gawd ty ^>w<^
TETOOOOOO

teto mentioned
Hello, I like element catto's, it's fun, could you make a official mobile version please? :3
not official but i made one
and its very bugged
atleast i can play
:D
I changed to the sun and it caused everything to explode, destroying earth in the process
10/10 game
my mac fking rejects it cuz is thinks it's malware
macOS tends to do that when it doesn't need to...go to settings->privacy and security->scroll down to the Security section and there should be a notice about Element Cattos being blocked, there should be a button to override/allow it
PLEASE do not set fusion threshold to zero
ya i did that, it went fun
how to summon cattos ??? i cant get any
space key
thanks
game is peak. i almost crashed my computer makeing a impossibly big element
it keeps crashing for some reason
less than one day and I already beat the game /j
adding a single proton to this thing makes it disappear.
given the density, i could easily carry a lot of it
but i'd probably instantly die
i fear what will happen if i enable all the settings
further observations:
I have discovered an even more disgusting creature...
how in hell
it's easy
note that in the first stage, if the dupes shoot really high, or if you decide that it should be enough, you should probably count how many it takes for them to delete
if it's over five, continue until it's not
further note that if you do it correctly, the lesser one should almost never have to be cloned in the second stage, rather that it will always be smashed at least once until the difference between the elements obtained from smashing other elements is no longer proportionally negligible, that is when there are two different, definitely periodic elements, then the lesser may need to be cloned.
