How to Play
Keys can be mapped in the settings dialog from the main menu.
This is just a demo, so there isn't much to do. You can pickup a handgun and a shotgun, move the character, kill things, and die. Also, clicking moves a white light to the cursor's position.
If you don't like the control scheme, you can disable key aiming from the settings dialog from the main menu (uncheck the 'keybased aiming' checkbox.)
