A really fun premise with an... oddly horrifying execution? The ambiance is quite unsettling, haha (in a good way). I like the mechanics of jumping around and playing keys, but I wish we were able to play more than scales (despite the fabulous play on words). Could've been fun to play a few basic songs; perhaps they are in the game and I just didn't reach them. Excellent work; I have no real notes other than I want more!
