I beat the game (level 20 is the last level) with left arm darts, core magic, and right arm bombs. I doubt this is the best set up, but don't waste your time on boomerangs because I couldn't get past the 16th level until I replaced them with darts.
@Jillian because people who are really enjoying a game are more inclined to comment on it. The people who don't like it might just rate it low and leave. I'm personally not a fan of these games... 3/5
