Glad you enjoyed the game. I actually had to reopen it to remember what the menu song was, because I had not changed it from the default until I stumbled onto it at the last minute. It appears to be called Newpumped, by Antman and as soon as a I heard it, I knew it captured the lively spirit of the game. Probably would have found it an earworm if I had had it for the whole month of development though XD
