Really cute game idea and lovely art and sound, so overall it has a great vibe. but I'd join the others in saying that ultimately it gets boring quite quickly, as comparing the cards takes a lot of time and after a while you just get the same responses. I was hoping that eventually, there would be another consequences to my matches (my mind went to the times I had brought carnivores and herbivores together, maybe!) and I couldn't tell if there'd be an ending state so eventually, after trying to click through at random to see if the heartbar would max out and give me a win-state, I had to give up.
Could be really fun with more polish and if the gameplay was elevated a bit.
