Quite an original game in which all the instructions are conveyed through images and imaginary glyphs. I very much like the idea of the puzzle, and it's a nice brain cruncher having to make tea for one guest while watching out for what the other is ordering. Very nicely done.
However...
It's mentally very taxing, and it goes on and on and on... The counter of 636 just seems so horribly far away that I eventually gave up at the point shown in the screen shot. At each place of selling, you see the counter only inching towards the goal, and after a while you start wondering: is it worth it? The game only becomes increasingly difficult, and with nothing in the way of a reward in between, I just got the feeling I was being punished for progress lol.
It's a shame because the idea itself is very good. And I really did (through trial and error) understand what you were supposed to do without any form of text. But by that time I've already missed the precious low-hanging points that I missed out on because I initially didn't understand what was going on, and heard one customer after another sigh and leave.
So... I would suggest to have some rewards in place every so often, as well as save points. But, again the idea is quite nice. The atmosphere is also good, and the graphics match very well with what you're trying to do. Just a tiny little bit of tender love and care would have made a huge difference!
