I can't even tell you how much fun I had playing Zombies Shall Not Pass. The controls were sporadically unresponsive (for some reason, turning left was a lot easier than turning right?), but still challenging, and I thought it was a realistic zombie behavior simulation. After about 3 hours of playing, I realized it was made to be played with a special touch sensor. Dammit, I'm glad I had no idea. Be right back, I'm diving in again.
