Complete game with nice graphics, fun theme. It's interesting that a quick calculation based on 4 availables plants and exactly 3 different in a brew gives only 4 possible cases. Adding just one more plant would have made 10 possible cases, allowing the same plant multiple times would have allowed 20 possible cases, and both would have yielded 35 possible cases!
This game is definitely easy to extend to offer more varied (and difficult!) play.
Overall, an impressive submission even if I'm not sure why it triggered my Windows firewall dialog?
