I didn't like playing this game for a few reason:
A) PCs with multiple monitors are screwed when playing this game due to the cursor not being locked to the main screen.
B) The slight delay between your mouse and the cursor doesn't feel good or fun to use, and it feels like an artificial obstacle to overcome for sake of difficulty.
C) Stolen music?
D) A lot of the levels it was unclear how to complete them, especially towards the end.
I think if done properly this could have been much more enjoyable, but as of now it just hurts to play to an extent.
