I am going to change a bit my game in this areas:
1.game style is still doom like gameplay.
2.added few more weapons including knife combat system.
3.game will feature cartoonish graphics & doom style graphics( 2D spirits).
4.changed weapon location( from middle bottom of the screen to the right corner).
5. doom single player is not in progress( because I want to make my original single player & survival mod first, then I will make the doom single player).
