Well the multiplayer is really cool but it doesn't really show it off too well since all we know it could be LAN only. Anyways you really need to get some textures and explain to us what the hell this is suppose to be.
Other than that good luck!
It is multiplayer and is hosted on one central server, eg. a MORPG.
I could run there server on my VPS, give you a copy of the client, and we could play together in the one world together.
Also, it is a "sandbox" genre game, where you just build stuff. (Obviously there aren't any ways to get building materals atm, but once mining and such is implemented there will be)
For now you just walk around, chat, and farm etc.
I plan to add realistic terrain including water and such, then make it so you actually register accounts with passwords and usernames and have the server save your position and inventory. Then I plan on adding mining.
