This game was pretty fun. I haven't died yet, but I think if you die you have to restart, right? I think that's a bit harsh for dying. The game is fun, but I wish you could switch items in the store instead of having to leave it. It gets boring after a while because there isn't any variety in the levels besides the monsters. The item bonuses are nice. The bosses are hard, I only beat the first one and then was too scared to do the others. etc.etc.
