It would be cool if you could create enemies and then let them spawn in your enviroment or whatever , and let your stick try to kill him, or create your own level filled with traps , and bunch of other options...
these are just some ideas that popped out of my head , didn't really think 'bout 'em...
It would be cool if there could be a message board where people could talk , or someother nice features like that kinda shit
