There are several things that are really impressive here - I really liked the shadow the demonstrates the jump, and the zoom out to reveal the building was really cool
I had some trouble with the controls, and had a hard time executing the wall jumps. Also the fact that when you lose you need to repeat the entire start was a little disheartning
I think with more gradual difficulty this one could be really cool! I really liked the artwork and music, and the lighting gave everyhing nice mood
