I really like the theme of your game! I believe it was definitely an out of the box kind of idea. Although, I'm not a huge fan of how the penguin keeps rotating in the air after they hit a speed boost. I feel like it makes it harder to continue the speed after the penguin rotates vertically or even more than that. I would also implement some kind of pause menu or buttons to allow the player to restart, go back to the menu, etc. I feel like you're almost locked into the level after starting it and must wait the duration in order to be able to go back to the menu. Overall, I enjoyed playing your game! The theme and idea was definitely unique.
