Ridiculously addictive... like alarmingly addictive. Simple concept, but tons of fun. The rotating arenas, arena placement, and ice tiles keep things interesting.
Jumping Juan Flash should have been and easy badge. Also, I find myself doing some sort of head bobbing dance nearly the entire time I play.
Exp becomes useless for Hero once you hit the trials; hero becomes useless in trials. Seems like there's a pretty simple solution.
Overall, pretty fun, but the series needs something new and exciting. It's getting stale.
