To FlipLine's response about keyboard issues with laptops, I don't think its anything wrong with keyboards, I am able to aim diagonaly up-left but not fire. When i try to fire nothing happens, this problem also appeared with Crags as well.
found a major bug, after completing the Sewer Recycling mission and talked to Wyrstan, all controls goes unresponsive except the menu button. You're unable to move from the spot and trying to travel will not work. Not even logging out fixed the bug so I was forced to refresh the window.
I encountered this weird bug after I fought against Satan with God on Practice Mode, I started a new fight against Jesus in Heaven when this happen.

lol, when you complete all 35 waves it says "Good job! You did, you saved us all!"
The game is pretty good for your first try so I'll give it a 3/5 rating.
The original game is called Halloween Bowling, look it up yourself. You can find this game almost everywhere but this site is the only place where it has a different name.
