dubwars:
ok this game is really fun and i'm incredibly bad at it
it's basically geometry wars, except you don't control the weapons. your ship shoots out various lasers along to the music and you just have to dodge around and try to aim them appropriately. huge potential for sensory overload (electronic music, flashing lights, lots of movement) but i can see this occupying basically the same space for geometry wars for me, which is "game i'm awful at that i keep going back to for some reason"
