There is a game breaking bug in level 17. I really hate it when a game about solving puzzles suddenly wants you to play a timing/platform game. In level 17 when you finally make it past the falling hands you have to move forward to get a toilet to fall. In all walkthroughs I've seen you can just walk back and climb the structure. Not in my game. It freezes me where I sit until the old man throws a column at you. This is made worse by the fact that you need to replay THE ENTIRE LEVEL. Please fix.
