I agree. Haxel is nothing like minecraft.
Now I think your statement may have been made with sarcasm, but I can tell you these two games have almost nothing in common, aside from the way we have decided to use geometry, and even that is dramatically different in Haxel.
I can go into a litany of things that are different in the engine, in how the editor is constructed, how game play and story vary, the things you can do in one, but not the other etc; but I think I will leave that to the intelligent individuals who will be trying out Haxel, and let them their draw their own conclusions. I have absolutely no worries about the merits of this game!
