Wonderfully rich game that always has something new for you. People like to knock the UI, which is fair, but in a lot of ways it really works; full use of the keyboard severely reduces the bottleneck between wanting to do something and getting it done. Yes, lots of things are hidden in arcane menus, but there's not too many of those, and with time you'll have them down to muscle memory and designating a spare stray llama to be neutered in a tenth of a second flat. That said, it can certainly use reworks in some areas, but that's more a matter of keeping things consistent. Many menus have their own idiosyncrasies that raise the learning curve just a bit more than necessary.
Ultimately it's a very impressive and unique project that does things no one else has come close to, but mechanically still needs lots of work for a chance at the mainstream. Still very worth your attention.
GOAT.
