Am I the only one that never even came close to grinding and think the arcane levels are the easiest ones? Indeed, I just knew that you can repeat a level to get more XP after reading these comments...

Nice Game concept, but extremely badly programmed. The AI is stupid, the game lags like hell, even on a high-end computer.
BUT the song is awesome, so 5/5 all the way!
