It's an awesome submission! I really like the idea of replacing jump with momentum. Some more feedback:
- The sounds are very well chosen. They fit the game. It also was nice to hear the sound of licking I used a few years ago in one of my games.
- The music is fine. It doesn't immerse you in the world, but neither it is off since the pace of the gameplay is not fast.
- I liked how you made the tutorial, allowing the player to play around
Very well done!
