very cool game, and very ambitious for 4 days of work! I think having so much choice right at the start can be a bit overwhelming, especially since until you've played the game a bit you don't know what's worth investing in, but I really like the subversion that you have to try to avoid picking up XP to keep your powers active if you want to stay alive. Turns the pickups into environmental hazards (and the magnet pickups into a terrifying experience). Congrats on the submission, this is awesome!
