Wow.
I mean, from the music, to the art, to the use of shaders/post processing (I think), it's honestly impressive you made this in a game jam (and alone at that !).
The mouse controls are definitely smoother, but I like that you gave players the choice.
If I had to give one remark : I would have liked a way to boost your speed to fast forward through more tame segments.
Stellar work !
