Thanks for playing! As for the controls, yeah, it's a little clunky. It's a "tank drive" where A and D are rotation rather than strafing.
We originally wanted to make some enemies hide when not in light at all, so slowly turning around was going to be a game mechanic (and I didn't want to limit to just mouse controls). We didn't get around to that so you end up with the odd controls and no game mechanics that use it, unfortunately.
I had a lot of fun making the main menu though! It was my attempt at incorporating the UI into the world.
