The game just isn't that great. Press the same 3 keys, quickly repetitive song, miss 4 times and die. Its not really fun to play. I also have to say that the lesson just feels kind of flat. I get it has good intention, but it just isn't really felt. There's no time for it to sink in, and not much depth for it to hold much meaning within a game. It feels like just a game over screen. I would suggest holding off that sort of message for either a bigger game or an animation
With all the being said I have to admit the way the song is sung by each member with a different voice and proper programming to cut it off when they fall is a great feature.
