Very clever twist on the memory card game! I like how it's tied to a narrative, you understand quite quickly why you don't want to see a bunny in your harvest. Inteestingly, this couls also be transcribed into a physical card game!
However, I feel like it lacks a little something to the design. Since the cards disapear when we flip them, we cannot use memory for most of them, and thus the game just becomes a game of pure luck. Even remembering the bunny position has little benefit, since you're not immune to finding a new one. There might be a rule missing to prevent it to be only a chance game.
But once again, the core concept is full of charm and potential. Overall I was delightfully surprised by the idea, and did several games to try to beat my score. Good job!
