Is there something that triggers the door through the bookcase in the globe room to open?

Hi guys I've been stuck on the clock puzzle for around 2 hours. I know I'm an idiot but does anyone know if it has to be done to progress? I just keep getting stuck *cries*

I tried drinking the tainted water but I'm not even sure if I do any damage to it at all. Am I missing something?

- The game can Freeze at the pushing mirrow - The hallway with a knight and one with a spider sometimes play monster music without a monster - The room with the ghost (with a candle) sometimes locks your camera and you can't do much - You can break the game by picking up vases in painting path after the puzzle was done (because you can't put them back) - You can get the bone from the dog without locking the dog's head (unless you were meant to do that) ...

The game looks GRRRRRRRRREAT and is in the new releases but as yet no option to buy??? Is it out today or is it yet another game that will slip to another month and another date?? Any heads up would be great!! ;)
