My favorite thing about Game Jams is seeing all the different interpretations of the theme. When I pitched the idea of the game I mentioned luck to be a landlord.
As for "Built to Scale," we instantly went to dragons and business management.
Yeah dragon scales are definitely the most interesting concept if you want to go for animal scales, btw this is my first jam so I didn't really know how to rate before some minutes ago, will do that right now!
