Looking for someone to build a game inside lf2

[Bamboori]

first of all, building much more than a LF2 mod will probably defeat the purpose of using the game as your base engine to save time.
Second, if you want to create a commercial game, you will need to get permission from them (i doubt that though, since you want to include several webcomic characters for which you would need to do the same).

as long as you create a regular lf2 mod, you shouldnt need to worry too much.
