Cool idea and atmosphere! Picking up berries was bugged in the web version (seemed like the collisions had an offset) but worked well in the downloaded version.
I think the game really needs some sort of goal, because if I didn't miss anything, you're kinda just beaming animals to the curator without really working towards anything bigger. And you should definitely include some music.
That said, I think this is really impressive for a 1-person team and I love the alien models. Well done!
