Huh it should stop saying "You may undo" once you run out of uses-- I'll look into it. I don't remember a fluff ball-- in the intro, you say? I will definitely try to fix issues with undoing and softlocking.
And you may go into the meditate menu and use the "I am stuck" text box to get out, right?
The next update will be around January 10th, and hopefully it'll be fixed by then, if I can identify how you got your problem (*´꒳`*)
