The hardest game of the jam, and by far. I did not managed to beat the game, but i'm sure I came close. The boost mechanic was confusing, as it did not move the player along X or Y, but toward where he was heading, making spike gaps hard to cross. I think the air bubbles that the player can collect should be bigger, as they can easily be mistaken with particles.
I really like the game, really refreshing to have some challenge from time to time!
