I'm on Version 0.7.5
After I beat the floor boss (golem), the screen remained on the same floor but I could not input anything. I'm fairly sure this bug occurred because I had enough mastery to use Evolution Jades for four separate transformations but I, coincidentally, banned those four on that run. I'm assuming that the game checks for banned transformations before letting you choose an transformation to evolve, but when presented with no options, the game left me stuck on the menu without letting me do any inputs. When I unbanned a transformation on another run, the game progressed normally by letting me use the Evolution Jades. Great game btw.
