Bugs what I noticed: You cant play level 17 at all because there is no that black thing which you move around. So you cant play any further. When this happened I went back to level selection and then main menu which popped level 42 achievement. Then I tried to select earlier levels but that locked me out levels which I already have passed so I had to play levels again. Then I went to main menu and exited the game which resulted level 41 achievement. Those things are broken so please fix......
