Thanks for all the feedback, it's very helpful and motivating :)
@roaringcatgames: You have to be quick, and a little strategy can help too ;)
@Merijn: I agree, most assets need polishing, and animation too. Lack of time! We focused on functional gameplay and general art style. I'm thinking of using a proper bone animation system later (right now it's hardcoded).
After you send the animal into the grass: that allows you to grow new trees in case you're out. And well... that's pretty much it for the narrative part for now :) This prototype is more like a sandbox, with a few bits of story and puzzles. We aim at adding more of that in future versions!
