Headache....
Well, I just spent around five straight hours playing this...
I'm going to just hand over a "You Win" notification for managing to hold my attention and keep me playing LONG after the game stopped being fun. This thing has a heck of a lot of content to unlock... I'm still nowhere close to getting it all... maybe halfway? Geebus....
It is fun though. Definitely gets repetative after a while though, even with all the characters to choose from. And I really wish that either stuff was cheaper or there were more ways to get rings.
