I like that, played another game similiar to it earlier this week. Can't remember the name of it but you only got one look at the map and had to navigate to the end goal. Not a fighter game, just a puzzle but was still interesting to think of both.
I liked the way you worked this though, I started to rely on my hearing and managed to get all the way through to the last 5 guys.
Very satisfying way to finish the game getting to just beat up the last few :D
