I made a game similar in scope to this called "Lava Ice Run". I can imagine you followed the same Flappy-Bird tutorial that I did for reference. It's a very helpful and insightful tutorial, I must say! Lava Ice Run was my first original game, and I'm proud of it.
I think the most commendable thing in your project is your artwork. I like that your levels each had a different theme. Also, did you mix your own chip-tune, or is that an asset you found? If its your own, then I have to give you props for that as well! It'd be nice to know what level of work you put into your assets.
I found it difficult to get used to your game's controls. "Double Jump makes you invincible" wasn't the most intuitive thing for me, but once I discovered it, I felt like it was more feasible to beat all 3 levels. It was a satisfying ending.
Lastly, I liked your sense of humor in the game. My wife and I found the collar-bone breaking death comical XD
Good luck this jam!
P.S. is that an army of Donald Trumps in the third level? XD
