Short and simple. Really good music, controls like a dream, I wish the falling level gave me some kind of upgrade too, probably could have used a note on how you can skip through levels (I sat on the "collect all the albums" level for the entire duration the first time and only looked around for some way to get through it on the second). Finally, the big ominous door made me feel like there would be something through it, leaving a bit of an anticlimax when there wasn't.
Very good game. I had fun. Played it twice, even.
