Draw a single stroke, flip tiles from black to white or vice versa, and turn each single line into a solid color each. A Polarium fan game for the PICO-8.

Features 100 levels, and a level editor so you can make your own levels or play other people's custom levels. Custom level passwords are fully compatible with Polarium.

  • Arrow keys: Move
  • Z: Primary key (select menu item, draw and finish stroke)
  • X: Secondary key (go back, cancel stroke)
  • Enter: Menu (pause, go back, show hint)

Instead of Z/X, you can use C/V or N/M (if you use a QZERTY keyboard, for example).
