So I went till wave 15. One problem I encountered was the entity limit. I didn't take damage, so I didn't heal, and so the healing items took up the entire entity limit and no more animals spawned, so then I ran around eating everything as fast as possible to resolve the issue. You could create a separate entity limit for food and animals to resolve this. The gameplay is fun and cute, but it does get repetitive. I was hoping there was an end to the story and it wasn't just endless wave defense (pardon me if there was an end). I'd like to see a zipline to get from the cannon to the bottom of the island faster, cause walking all the way there and back is not super engaging. I'd also like to see different animals have different attributes or something. All in all a very fun game, and you should be proud.
