Thanks for all the nice comments folks!
1. For people who missed it, the score is on opposite sides of the window frame from each other. If I keep development going I'll make a custom graphic with the writing scratched in with lines e.g. IIII kills
2. I was going to make a 1 player mode but I much prefer games which encourage social interaction in the same environment. Also, there's that little thing of programming an AI...
3. There wasn't a sound designer handy unfortunately, but getting audio for the game is an absolute priority since it adds so much to the game.
4. There was a plan to add a speech that the president reads out giving the assassin a limited time to eliminate him. This would be displayed as a graphic similar to a karaoke screen, slowly passing through the words.
5. One thing I noticed from testing with my brother was that he spammed the mouse to try and find me in the crowd. Though the technique of his failed miserably, I'll add making a mouse click fire your bullet regardless of if you're on target. The crowd would run off, leaving the assassin exposed but since sniper's bullet has been fired, nothing to stop the assassin from killing the president. This would give a certain gratification to the assassin, as they could run around all they liked and taunt the sniper before killing the president.
6. May add in blood but might just make body limbs pop apart similar to lego instead to keep the game out of the mature section.
