Whoa. I there's a lot to hate. But I like it!
First thought: How do I even play?
Then, after disc[oo, "c" opens crafting table even after death...]overing I can craft: Yay, minecraft in 3D! But wait, minecraft is in 3d... well, a good-looking minecraft!
Then I dug into the wall (upon which I decided that you really need some shadows!), then dug through the wood-covered hole (good level design there
), then I basically flew a bit then my energy ran out then I died
So what criticism can I derive from this? The GUI with the feedback window made a great impression on me (albeit being unusable after death - all keyboard shoutcuts were still funcitoning!). Yeah, you need to work a bit on graphics. Also, I would suggest some kind of tutorial, or at least some message as to what one is supposed to do. The whole meaning of the game is kind of vague for me.
The strong points of the game were the possibilities. Being able to mine the ground in a 3D-game (that is not made out of voxels) is something I've never seen before (but it does probably exist already). I think this game has a great future, and a lot of more content that I never got to explore
And, physics!
So, in a nutshell: A really fun playground with lots of stuff to do, but it also needs someone to tell me what to do.
Good luck in the future development.
