I really likes the character artwork! Especially when you're playing the piano keys. I made it to the end. I got a really really big piano key. I think I won?
Woohoo! It took me about 6 tries. Once I got a good handle on the controls, I was really zipping though it. This would be a fun game to speed run. If you ever make any further improvements, I'd request adding a message at the end telling you how long it took and if you missed any keys.
Really great entry!
