Only played for a few minutes the other night, getting used to the controls. The arena seems almost frictionless, so the physics are fucking with me. I'm plowing into enemies when I'm trying to shoot and strafe. It's a lot of fun and the soundtrack is great, reminds me of Atari Teenage Riot.
Also, the Nightmare_DatauserSessionVariables file contains your user name, so I tried updating that. Now I need to get a better score to see if that posts to the leaderboard.
Have I mentioned this is a lot of fun?
