TUG is a game with big goals and a small start, but that's just more stuff for it to work up to over time. The latest update for the game's backers shows how far the game has already come even in its early stage, though, with the game already beginning to build upon and improve its overall infrastructure. The latest update highlights that third-person models are now partly in place, with first-person animations and some third-person animations working correctly.
The game's networking is also in place, but at the moment it's only a bare-bones implementation; players can host servers but no central server architecture yet exists. The update warns that it's also largely untested, since that is part of what the testing environment exists to facilitate. There's also new biomes, new crafting, and physics -- a far cry from the initial exploration demo. It's still small, but every update makes the game just a little bigger.
