Cell Machine

Arrange cells. Build machines. Destroy enemies.

Each cell on its own has a simple function, like moving or spawning other cells. But when combined, more interesting behavior emerges...

Made for the GMTK Game Jam 2020 with the theme "Out of Control". In the game, you only set the initial conditions on the grid of cells. After pressing play, you can no longer control anything. Instead, a simulation unfolds, with each cell behaving based on its own set of rules..

The game is based on cellular automata like Conway's Game of Life. Atoms, molecules, cells - do they behave deterministically? And if they do, does combining them together change that?

Also the cell based machines you make in this game can grow exponentially, literally becoming out of control.



Rearrange cells in the build area. The goal is for them to interact in a way that results in an enemy cell being hit. Press the play button to run the simulation. Press the step button to execute one generation of the sim. Press the restart button to enable editing again.


Mover - moves in the pointed direction

Push - can be pushed in any direction

Slider - can be pushed only in one direction

Rotator - rotates adjacent cells 90 degrees each generation

Generator - Duplicates the cell behind it each generation

Immobile - Does not move in any direction, but can be duplicated by a generator

Enemy - Overlap any cell with the enemy to kill it

Somehow this game is funny! The mechanics are fun and easy to use and for some reason its funny when i find out how it works and what it does. Plays great! really a fun little game! Always amazed where some people come up with! No idea what fantastic feedback i can make no how to make the game better really, maybe a way to skip a puzzle if you get stuck since it does get hard(er) towards the end and not knowing how to solve can be frustrating. But no idea if its an idea to have like a hint or skip system… If you have the time i would love to hear what you think about my puzzle game: https://guldor.itch.io/citybuilder


I think a sandbox mode and more levels would be fun.
