Really love the concept of this game! You did a great job with the speed buildup and obstacles of the game. The tooltips inside of the game are also a great addition.
For feedback:
- Music and SFX will make the experience much nicer
- In level 5, I fell down at the start and didn't respawn
- Sometimes you're unable to see where you need to go. Blind leaps are not really ideal to have, so having the camera show more or zoom out when your speed is high could help with that
Overall, I think the main thing that's needed in this game is polish. Music and SFX, along with particles, would make the gameplay much more satisfying. That being said, you got a great concept to work with, and it's amazing that you could accomplish this solo in your first game jam. Great job with your submission!
