Eh, it's okay.
Found it was happening too often that amanitas would spawn right next to, and along the same arc as, normal mushrooms, making for a damned-if-you-do situation, so that was a pain. The achievements that pop up seem pointless, since they reset with every game. And then there's the complete lack of variety; playing this game for 30 seconds seems to be the same experience as 30 minutes. The idea could stand to be developed further.
