Hi Friend!
I'm sorry to hear you're having trouble with MageQuit. I talked to Breet, and he said that right now the game can sometimes run the CPU pretty hard. This is on his radar and is something they're looking to address in the patch later this year. He's pretty sure it's related to the custom physics layer he added for the game's slidy-ness, and has an idea for a fix in mind =]

That is really weird! I'll send this comment to Breet so he has this info when he continues to look into it! Thanks for following up =]
