The physics is crappy and i just about impossible to maneouver pieces when there are more than 4-5 on the board and you have to balance them on top of one another.
The difficulty of this game stems from the fact that its just bout impossible to move anything rather than the fact that the puzzles are hard.
Because of this, the game is more annoying and frustrating and there simply isnt the need to come back after you finish.
I dont suppose most people will actually finish this game before they decide to give up >.<
Just my 2p.
I insist it is something wrong with the computers or some other personalized detail because, for me, its been loading very smoothly since it was released.
All those fricking ppl for whom it wont load and are giving it 1/5, remember its ur comp at fault and you aren't supposed to rate your computer, just the game. So play it, like it and give it 5/5 :D
