nice game, i liked a lot of the background graphics. not 100% sure what i was supposed to be doing :). i'm guessing finding all of yellow squares (found 3 or 4). liked how you could hear them before seeing them, like for one of them knew it was above me, then had to find out how to get there and another the same when knew it was below.
liked how notes were played on jumping, i didn't notice that at for a while, just thought it was the music :). also there was a section where a drum beat started, didn't really find out why tho.
