I'm addicted to this game...If you haven't heard of it, it's basically like Binding of Isaac + the Old Doom games...which means randomly generated levels, fast paced twitch based FPS shooting, and Nazi demons, on a boat... yeah. It's addicting, to say the least. I've had a lot of fun with it so far though, and for only a $6 game, that's awesome. It's always a pleasure to be surprised by indie games!
