Well on the part that you have to choose a path to fall in to it happened to me that the character remained white even after respawning, and it wasn't really clear what you had to do in the boss fight.

it seems that you are interested in solving the bugs, I have encountered another bug after the part that I have to choose a path I reset by pressing R , the game respawned me at the beginning of the level and the music turned off only playing is the sound effect.
As I said I really enjoyed your game.
