Too many glitches
I rate it an 8 because it's a great game in itself, sticking true to the awesome concept and style of Sift Heads. In fact it would have been a 10, if it didn't have so many glitches and problems. A lot of times, as others have pointed out, it freezes. And at one point, I couldn't get out of a room no matter where I clicked. This game has to be fixed to be truly appreciated for the genius it is.
