So after listening to the game of the year deliberations and hearing Jeff's recommendations on VVVVVV I decided to pick the game up off of steam for $5.  I have to say, that first of all, yes-the music is totally awesome.  It's fast paced and makes you want to keep playing and playing.  Secondly, the game is awesome.  I love the super-retro look and the game play is great.  I did have a bit of a time with some of the levels with the keyboard but overall I loved the way the game controlled.  I was really surprised how much sensitivity and control you had over your little dude.   I enjoyed almost everything about this game.  I fully recommend it to anyone interested in either chip tunes, retro gaming, or just gaming itself.
