24.07.2022The game has grown a lot since 2017, we have so many more animals, new biomes (a swamp even), and accounts, skins, pets, it's really grown. It's very community driven, most things in the game are made by the community. (I made a little terrain coloration) We're relatively small of a community, and it would mean a lot if you checked the game out again.
