I was talking story wise, doubt it could be fit into this game, I feel like you already have a lot to work with here.
Maybe if you for some reason wanted to make an exotic hotel simulator XD.
Eitherway same with my characters. A little taste of the whole Roach Hotel Concept

If you are curious. Also I got an archive account so woo. Eitherway I'll be adding more of my works to it in time.
Oh might be a bit far off, but what is your idea(s) for your next game?
