I cannot think of a worse weapon than this kitty. Take a peanut shell for example. While it might do less damage, at least I don't have to chase after it and kill myself before I can throw another one.
There is no numlock key. My Fn key is only for pressing the "F" buttons (F1, F2, etc.) No matter how many times I press Ctrl+F11 or Fn+Ins or anything like that, nothing happens. Any game that requires me to download a keyboard macro is not a good game.
I feel like after a certain point, the game starts playing itself. With 2/3 of the attacks being omni-directional auto-fire, you could literally leave the window running in the background and it wouldn't matter.
