Great piece of art and audio.

Design and experience wise there is a lot of room for improvement on mechanics, animation, interface, responsiveness, collisions. 

The controls need to be improved, and the platforms sometimes were kinda glitchy, a introduction could be made to make the game easier to understand, but I see that you uploaded one day and a half before, so I can see why you did not have time. The audio was really good btw, you could feel inside the game/ nightmare. Good Job.

Very glitchy movement. Platformers are hard to get right.
