I decided on simple laser weapons (which travel at the speed of light), which means that you won't ever see the ones that hit you until it's too late :D
Oh, I made it a split-screen two-player game so that you can see for yourself how the two players can see things totally differently. (but, maybe the screens are on the wrong sides...I'll fix that in the next version :-X )
I've not actually tried playing it with anyone yet; I assume that the gameplay potential in its current form is rather minimal, but I think it's still a little bit fun, and I might work more on it in the future.
And, I have two separate versions (both with sources: the mac ones should compile on linux machines as well...).
Player 1: Cursor Keys and Spacebar Player 2: W S A D and F
there is some additional discussion of this over at the original tigsource thread.
