Cool game, I like how you used the theme here in regards to consumerism.
When the bill got very high, having to wait for costumers to walk up to do the minigame got a bit tedious. I like that the minigame speeds up but I think you may have needed to add a little flavour there since it's the only gameplay mechanic.
All the art is really impressive and I love all the analog sfx, the game has a great and depressing vibe.
Nice work.
