Wow, this idea is new and intriguing and there isn't already a bunch of these type of games out there! 5 out of 5! /sarcasm off. I mean seriously how many times can people make the same games?

Great song, I copied it from sheet music and added extra chords, leave me a comment on my profile with what you think about it.
I personally think it would be better if you didn't have to start over as soon as you lose. 1/5 right now for wasting my time, 3/5 if you make it so you can restart a level if you die. =)
