Cool, but not sure if I could listen forever.
This was pretty nice. If this was in a game that I was playing, however... I think that shaker sound would drive me crazy. Don't ask me why. Repetitive percussion just really gets my goat. I would kill the shaker about halfway through, then bring it back for the last few measures.
But regardless, this would go frigging PERFECT in a puzzle game, so for what you were trying to achieve I think it deserves a 5/5 10/10 because you did it.
