Good job with the prototype! I played it, and at its current phase, it is quite fun to experiment with stuff to see how they react.
I got to discover 43 cards out of 46 total, I, unfortunately, could not figure out what to do with the purple bean-like creature. The maximum score I got, I think, was around a hundred. I would like to see the environment more alive. Flies were taking so much time to eat a single moss, for example.
I hope you continue putting more work into this prototype, would love to see where it goes!
