Agreed, the soundtrack is class, suits it down to the ground.
Funnily enough I got Super Meat Boy a few weeks ago after being hounded to get it by my mate, I'm glad I did definitely. It's a ton of fun and also nuts like Hotline!
I've not played Braid however I keep meaning to, it's one of those. Sadly I know the twist at the end, do you think that would take anything away from the game if I play it?
