Enjoyed it a lot! It’s so calm and meditative, suits the tea theme very well. I actually liked the way it didn’t punish the player too much. The customers were nice, patient, and mostly supportive :D. Would be nice to have some variation as the game goes on though. Maybe time/days passing, customers asking for more specific requests, small goals and progression, etc.
The kettle temperature control confused me a bit, I didn’t realize you could turn them on/off. Ended up serving one customer with 20 degree tea because I thought I could at least start using that pot again afterwards XD. Some visual indicators would be nice there.
On an unrelated note, having to drag and drop the kettle onto the customer felt like I was pouring boiling water onto them. For some reason I couldn’t get this image out of my head.
Great work overall!
