Not much to do. The first person perspective will likely cause someone motion sickness with it spinning around randomly. The background doesn't feel like a sphere but rather like a flat plane while turning. Music doesn't fit. And like Why485 said, the physics needs more work.
The menu needs work. There's a load option but no save option? I like the graphics, reminds me of dungeons and dragons online. It's pretty neat that I can destroy and nab just about everthing in this game.
Strafing sideways is a bit awkward. Jungle music is pretty good. Skipped the tutorial since I could. I eventually found the base camp. The next day I got mauled by two grizzly bears.
