After level 15, while i was just finishing 16, the bug kept slowing my pc down until the explorer ended the process...I'm not sure i'd avoid that if i tried it al over again

Well, my friend just got to level 22. He was getting the message after every move and had to wait a few minutes so he didn't attempt level 22.
