Yup, that’s pretty much just a technical demo and a very heavy at that (enough have been said on that regard).
To underline, we have 10-15 mins of content of a rather crude make. There is no story line or narrative as you cannot really count those dialogs as that. Several animations with couple of them being rather static, few generic locations (the wall art is a nice touch), basic energy/health/hunger system (a solid base to set, but right now recommend leaving at that) and… lots of bugs.
Some of the character models are good (except MC… GOD it’s hideous!), but the lifeless facial expressions bring those efforts down; though this is not something this game should be concerned about at this stage.
syslink posted a video on the first page that gives a general idea of the current state of the game if you want to spare yourself a 17 GB download.
I don’t have a problem with this copying/following the idea and premise of Darktoz's M.A.N.T.I.S. (the more the merrier, right?), but if the dev is serious about getting support, they’ll need something a bit more defining than the 3D models until they become top notch, imho.
One thing that is really playing against the dev here is the choice of engine… Unreal is pain to work with if you don’t have a solid knowledge base, and judging by some of the bug encountered – that might be the case (though if it is in fact your first project – kudos to you as it could have been a lot worse!).
Not to discourage, but the nature of the project is an ambitious one and will require a lot of early investment to get the desired friction.
With all that said – still a good job! Keep going!
P.S.: Seriously, change the font... it's just... no.
