You get the theme right and particle effects are great!
I see no point in providing that 3D goods to those customers, can't do anything with the coins?
I would say, pretty good game that can be greatly extended, keep up the good work!
Thanks for the feedback! For the jam, I decided that the coins would sort of act like a highscore system. If I work on this any further, I plan to add stuff to spend the coins on. :D
