Fun game. I also ran into the freezing issue. It seems to occur most often in the skill tree menu. It froze 3 times trying to purchase midas touch. I also had a few freezes in the blacksmith menu
I looked again into it and i might have found the issue. Thanks for the bug description!
I've uploaded a new version. As far as i tried, i am not getting any major freezes anymore, which would stop the game.
