Great approach to the theme. Really enjoyed it. IMHO everything is great in the game. The music, the art, the animations, the dialogs, even the important notice on top left (where the clock is) - Thats a really great UI/UX. Respect for that. Minigames were also pretty good. The game already feels like a great product.
I did encounter one small bug tho, but it didn't affect my opinion on the game. At some point two customers went to the same position and it was a situation that both of them are inside of each other and I gave wrong order to them.
