That was fun music!
The controls are kind of awkward and hard to use though. I was surprised when the character starting flying while holding the up arrow instead of just jumping. I felt the movement speed is too slow. The character also fell through the platforms sometimes.
You should describe the controls to use in the game description. It took me a minute to figure out that it was arrow keys only instead of wasd or mouse.
Just curious, did you use a game engine? Which one?
