Pretty fun game, played it for a while. Music and sound's good, like the concept of being able to pick what special ability you had, though the red ability's more useful than the enemies than the player, while the blue is more useful for the player than the enemies.
Smaller shapes could also escape being eaten by just hugging the walls and corners, though, which is a bit weird.
Overall, the game's quite good! Definitely a good second jam game.
