I made this today and yesterday. Mostly today and I think it's neat.
THE BASICS: You are this cute little gangsta guy that shoots other gangstas. You have 4 weapons, at first you can only use one but the others pop up from time to time. Kill guys and don't get killed. It's only a demo and has not goal or anything, just shoot.
Use you mouse to aim cursor and WASD to move. The title screen has instructions.
OTHER STUFF: At first you start unarmed. I did this because I thought of making this an adventure/rpg shooter game and you had to hide the gun in populated areas with normal people and cops. I don't know what direction I'll take this game, if any. It looks like it could be a kick-ass online multiplayer game but beats me how to do that and I am afraid of trying.
The enemies have Artificial Stupidity.
The game uses a weird resolution, something like 300x250, for distinctioness. Hope that doesn't kill your monitor.
