Managing the store is a gold idea to extend the game! Set hours, attract customers, order food, set prices,. I'll have to try Dave the Diver sometime.
I'm a huge fan of 2D games and grew up on SNES so my nostalgia always pushes me this direction as well, but our coder, Dreamcastic, grew up on 3D games PS1 era so we thought a 2.5D Paper Mario style was a fair compromise. Our artist, Rumi, spent the most time on our solo customer, Chris Chan and his 6 different expressions, and we were quite impressed with their work. Once you get to really know Chris Chan you'll find he's more than meets the eye ;) (and quite the charmer)
