About
The forest (filled with suspicious quantities of ammunition) has been invaded by cellular automata! Use various weapons, abilities, and upgrades to purge the machines in the forest before the machines take over.
The enemy machines in Yawnoc are living on the rules of Conway's Game of Life and other cellular automata. Will you carelessly attack the machines and die to a creature of your own making or destroy the machines with precision and restore peace to the forest?
FIGHT CELLULAR AUTOMATA
Fight machines from different automata algorithms including Conway's Game of Life, Brian's Brain, and LowDeath. As you progress through the forest, the machines will begin to follow different cellular automata rulesets that change their behavior. Master each algorithm to learn how to quickly exterminate machines in every area!
POWERFUL WEAPONS & UPGRADES
Choose from tons of weapons and upgrades to give yourself the best chance at pushing back the machine invasion! Every weapon behaves differently with unique abilities that suit different enemy types and combat styles. Over 50 different upgrades are waiting to be discovered!

ENCHANT, ENCHANT, ENCHANT!
Permanently upgrade your weapons with powerful enchants! Every weapon is truly unique to you through enchanting with thousands of different enchantment combinations. Enchantments persist between runs and can always be improved! A sniper that calls down lightning strikes on your enemies? Yep! A sword that gives you super speed? Of course! A shotgun that raises up an army of centipedes? Why not?
PARTNER UP
Join up with the locals to increase your firepower! The forest's residents are fed up with the machines and eager to assist in their extermination.

Someone used Conway’s Game of Life cellular simulation as a premise to make a game? Ok, you got my attention, I know about it, I follow Numberphile channel for decades. Yeah sure I want to play that. However... What you find here just doesn't... oh boy. There is no introduction to the game, some small random npc dialogues, oh you have a gun in your hands for no reason? Go and shoot some "machines". So you find a portal on that initial hub area, no info, you enter that portal. And you shot some cubes, for 2 or 5 minutes... sometimes you're pulled into a matrix world for no reason, zero explanation, kill a couple of constructs, then back to "reality"... why? Who cares! Developer didn't care, why should you? And then THE cherry on top, the ultimate sin in video games? The moment you destroy the last cube piece on a level, you are pulled back to the hub area, against your will, leaving ALL that currency and items around you! That's a newbie level design sin. I don't recommend this game, but I'm leaving it as positive for John. Refunded, return my 2.49, since I cant have my 0.5 hrs back. Damn, this one pissed me off.
This game is honestly so simple yet so fun. I got to wave 14 my first try and I so badly want to keep playing. I am super responsible and go to bed on time so that I don't miss my college courses the next morning, however, this game is making me contemplate staying up all night and just missing my classes. Not to mention this game is such an inspiration, I found it by watching your youtube channel and in all honesty this makes me want to make my own! I love it!
Good game to just sit down and unclutter my brain
Nothing against real life Brian Silverman But I hope that "Brian's Brain" gets dementia.
Great action roguelike, definitely a challenge to play. These enemies do some damage.

I think this is a great game for anyone who's into roguelikes, or bullet hell games. I really enjoyed my time with it so far, its really polished, the music is so vibey, and i love being able to buy different weapons, every time i see a new weapon in the store, i get even more excited to keep playing and to see what kinda playstyle it has. Its super chaotic which i like and everything has such crunchy feedback. At this price for me this game is a no brainer.
Very good game. The graphics are excellent.
Really Good
