This game is my first Pico-8 game. It is also the first game I manage to finish after a few attempts with game engines such as Unity and Godot. It took me 1 month to complete the first published version. The Pico-8 restrictions allowed me to define a manageable scope for this game. In the end, I used the entire space available in the map editor and the spritesheet editor. The code uses every token allowed.


v1-beta :

  • Update rooms (adjust difficulty on the main path)
  • Fix seconds and frame counters not being properly saved and restored
  • Auto-save state when close to a spawner tile instead of saving when changing room
  • Show which button to press to teleport and decrease button hold duration
  • Increase jump buffer duration and coyote jump duration (grace frames)
  • Decrease walk acceleration to make it easier to move by 1 pixel
  • Increase lamp range
  • Red cube won't spawn if there's no saved data
