Hey schme, what a cozy game you have there, here are some comments about the game:

• Some error sound would be nice, the text can be easy to miss when you need to do something 
  before for example.
• The time for the tooltips to appear should be shorter, I didn't realize you can see the brewing times and degrees in the tooltop. I think it would maybe better to have some kind of visual or audio indication that the tea is ready or gone bad, at least i would have preferred that instead of having to remember the times. Also is there a way to see what tea is on the table brewing? Because it would be much easier to manage the brewing teas also if I could see it.
• I think the times for both the orders and teas could be shortened, 2-4 minutes in game is very long in my opinion
• I think the game also needs more life, maybe customers coming to pick up the teas or people sitting at some tables talking or something.
• I would love some sound effects for the kettle, cold water and maybe even starting to steep the tea also
• One small mention from me is that when you start the game, you get the orders top right, but myself for example I don't know anything about teas, so I had no idea what it means that there is just "Assam" progress bar ticking down. So maybe having some text like Orders: or something would have helped there, but I did figure that out quickly that those are the orders.

Overall I enjoyed the controls and graphics and vibe. The game feels cozy with the music and cat sleeping. Everything seems pretty intuitive apart from that tooltip thing I mentioned, because that is quite important to know the steep times and temperatures.
