A concept for the next update, Unlimited Mode. Basically, you'd be able to customize every aspect of the game to your liking, with no regard for balance. Additionally, however, this mode also introduces the possibility of adding new characters for this mode exclusively, just for the sake of it. The only reason the guys from Hell Mode's challenges are exclusive to it is to not screw up the base game's all max mode.

Basically, the inclusion of this mode would allow for adding a lot of cool stuff without compromising anything about the base game's balance. Before i continue working on it though, I'd like to know the general opinion of you guys, do you consider this mode a worthwile addition?
