Is there another ending other than getting caught? I did that three times in a row and am quite uncertain, but I digress. The game is quite funny. Why an elephant likes eating fried tilapia I'll never know, but it's quite a funny churning out food for the animals. I ended up using a separate cheat sheet just to help myself find the correct recipe, but I still ended up doing 13 animals only.
For some criticism, I would say you 100% should put the recipe in the game, and probably on the same sheet you put the food preferences too. I don't even know the recipe exists in the first place. It feels strange seeing animals such as dogs that prefer bones and require two bones at once, and the sprite also changed into slop for some reason, which threw me off at first.
Anyway, this is quite an interesting game. Good job!
