Love the concept. The wrong input sound was too annoying though. Is there a way to figure out the new controls without guessing, or am I just stupid? The zombies really gave me a hard time. Love the presentation!
You do have to guess, but once you find out *one* key, you know the others are just around it, in a "T" shape just like WASD ;) (The shape can be rotated though, so for example AXSW is a valid possibility!)
