Cart [#47164#] | Copy | Code | 2017-12-06 | Link

This is my first PICO-8 cartridge, and my first time with Lua outside config files for i3wm.

Petri is a puzzle game based on a problem I've been obsessing over for a few years.

It's Conway's Game of Life, but run backwards. It's pretty tough, even the 6x6 board.

Let me know what you think.


  • removed todo in tab 1


  • fixed cart data bug. defaults to six if not present
  • fixed graphical bug after resizing to 6x6. tiles deliberately zeroed now.


  • better difficulty levels
  • created levels
  • save/load/share in-progress puzzles
  • notes/single-cell test mode
  • more thorough instructions

Damn it's really hard. I can't figure it out. Maybe start with a 2x2 board and go from there! Super cool concept.

I thought I understand the Game of Life pretty well, but doing it backwards like this is super hard.
