I just saw this and downloaded it yesterday, and I'm so hype for the full release. I played the initial game roughly a year ago and it's something that I've gone back to pretty frequently, despite how limited it was in terms of features.
I adore games like these, and I'm very excited that this concept is being taken further out. And now we have ducks!! Incredible.
One negative thing to say though, is that the pathfinding for some animals isn't very good. My crawdad frequently died of starvation despite plenty of dead critters hanging out on the floor of the pond. Fish rarely ventured beyond their breeding grounds too, meaning that some parts of the pond got insanely crowded, while others were barren.
But overall, this has left me wanting more! I'm very much looking forward to seeing what sort of things you guys create in the future.
Happy trails!
