There was a time when I was really into the original Diablo, and like many players I thought I was going to wear out my mouse with all the button mashing. Mad Acorn is that game for my iPod Touch. In fact, sometimes I get worried that I’m going to leave a finger indentation on the screen where my thumb is most active. Then I forget about my concerns as the next wave of bad guys roll by. I’ve never been a fan of Tap Tap Revenge style games, but when a game in an established genre tightly integrates music into the mechanics, that’s a whole different story. Not to mention that Mad Acorn is the cream of the crop in that regards.
