It only happens on the knees?
Get stuck how, can't choose actions or can't do anything?
had the same thing happen, I just played the puzzles for a bit, gettin reds, and when i exit and click on the skirt the text will display and then everything kinda just freezes? like it doesnt stop the game but it gets stuck on itself? idk but i had the same problem so figured i'd let ya know. It might just be a problem with playing in browser? it sucks when it happens and ya have to restart. (thanks for the cheat mode, it was a little sad when I got 6 reds for that to happen.)
