Hello Everyone. This right here is the tool for building levels in SeppuKuties, which will be released later on today. I wouldn't really judge this one until you've played the game proper, but here it is for those who like to toy around with things.
I'll have this description updated once the full game is uploaded and in the swing of things.

Controls
Mouse controlled level editor.
Arrow keys to run / jump in game.
Shift to commit suicide.
