I like the platformer style of it!
I did have some problems regarding the aspect ratio. It seems to be zoomed in and feels a little weird. The options buttons doesn't seem to work for me, though it might be doing something offscreen that I can't see. The window does say that it's on DEBUG, which may explain the problem.
I like what you did with the music! I should mention though that the audio source is pinned to a specific part of the map, so when you get to the door to the right the music only plays from the left speaker.
