I received my game today. I just finished playing for the evening, and I really enjoyed it.
While Insanity is definitely a port of Berzerk with few frills, Pyramid Plunder feels like it has a little more of its own identity separate from Pac-Man. The Egyptian theme is quite unique for this genre, and works quite well, and the power-ups that you can activate on command add a good layer of strategy that wasn't there before.
Very nice, Arkhan. I can't wait to try Atlantean.
