I absolutely love the paper cutouts with 3D shadows! The black and red color scheme sets a good mood and makes the characters pop. I like the designs a lot, there's some unique personality to every person, I wish they had a bit of story so I could get to know them better. Really wonderful art style!
There's no music, but the atmosphere and sound effects make up for it.
Plenty of bugs with customers not appearing and employees getting permanently stuck, but no crashes, and the boss can still be payed if you've bought at least one vip before the other stuff breaks. There's also some loose floating pixels on the customer's arm.
The gameplay is enjoyable, having the player as a more proactive manager in a simulation game isn't done often enough.
Even if the project is not expanded I hope that you'll have a chance to polish it a bit, because it's very close to being a very fun short game already!
