The atmosphere you created is fantastic. The controls feel great, and the game does an excellent job of creating a fun sense of pressure that fits the gameplay perfectly.
The only thing that frustrated me a bit was that I sometimes accidentally started making a cocktail instead of talking to a customer. Once the action started, I couldn’t cancel it, so I had to finish the drink, and if I already had one sitting on the counter, it would get replaced. I don’t necessarily see this as a design flaw, but I do think allowing the player to cancel the action or prioritizing customer interaction could make the gameplay feel smoother.
Other than that, I absolutely loved it. It’s an excellent game, especially for a game jam. Great job!
