I had a lot of trouble understanding how to play… an instructional image on the main page would have helpful, I think, to explain what all of the different buildings do. I eventually figured out that you had to bring all of your bunnies into the green-roofed building to protect them between waves.
I think the core concept has promise, but it’s really unclear how to play, and even a little bit of guidance could really help the new player experience. I did like the sea bunnies and the experience of amassing more of them though!
