I wasnt sure how the mechanic worked at first, the first time i just got to the end and didnt really know what i did to beat it, but i played it again and saw how it worked. It was a cool concept though, and the story had some thought to it which was nice. I liked the piano as well, but it looped way too much. Would have benefitted with a little longer level. also the gravity on the player was way too much for me
