Forums - DOS adventure platformer

Alright--there's another one I'm hoping to find out: stop me if this one is like extremely obvious and I just don't know it.

It's a DOS adventure platformer with a stage that looks like Donkey Kong ( except I don't remember any slopes ) but I'm sure there are ( vines and ladders? ) and it's a multiplayer game ( where the objective is to kill eachother ) too--and there may be projectile weapons--and the characters somewhat resemble little stick figures--and maybe the characters are color coded ( like red and blue ).

Edit: I remember another detail about the game--there was a level editor!
