The general aesthetic is really nice, and the concept as a whole is fun.
A tutorial would have gone a long way, even just text on how to interact with the customers and hand over the drink as that aspect left me confused. It could also be a bit tedious to make the drink since it seems like I had to tap the glass with the correct ingredients.
I see the vision and with a bit of refinement could be a really cool game.
Good luck with the project and nice job so far
