Thanks for the feedback. I will remember to put in my next games.

I specifically recommend the numpad, because those keys are closer to the mouse on a normal keyboard (and people normally use the mouse for shooting like this on a pc). The current controls work well on a laptop without a numpad. If you'd go further right, then you'd hit keys that surely change between different languages, and more annoying than the swapped y/z on some keyboards.
