Well, it is a brew game alright! I lost the first 5 customers because I had no clue how the game worked at all. The little booklet in the bottom left didn't do much to alleviate that. I eventually figured out how the game cycle worked, and after that, I was able to get mostly 'OK' ratings. I got one perfect rating, though, so that was fun. I think if the game had a better explanation, as well as more descriptive UI, the game loop would be much easier to understand. A lack of sound also hurts the game, but not having that is understandable.
Ultimately, it works! Good job.
