Great Game.
I'm surprised I haven't reviewed this game yet!
Anyways I found this game just simply fantastic.
Only thing I'd like to see is more int he ways of music, maybe some your character would find is a radio or something (I know it's a cheesy) and it'd play music from your own files or a playlist you implement into the game itself.
Only thing else I'd love to see is more levels, but since you're working on a different game I guess it's not gonna happen.
Awesome game nonetheless!
