I decided to add quick polish after the end of the jam for future players enjoyment:

• microsoft gamepad support: press G on keyboard to activate, by default it is off
  • analog allows some level of control over speed
  • regular directionnal cross
  • A, B, X, Y to pick friends
  • A or regular up to jump
  • L/R to toggle music during levels
• rework on worm segments, and slight animation to accentuate contrast with regular blocs
• a little bit more emphasis on blocks that can be entered in
• fix of a bug where blue friend could not cross small gaps 100% of the time

Have fun ;)
