So, um, as a demo that's somewhat good, but as standalone game - not so much.
* Story. What the actual hell is happening? If I'm correct, PC becomes a conscript, then goes through boot camp (which seems to be local amusement park's shooting range), then stand behind some barricades and fire at unarmed civilians, whose only crime was, supposedly, dressing in t-shirt of wrong colour or growing a moustache, constantly named brave for that, and... that's it. I see no plot here, not even a semblance. Papers, please was not all about paperwork or occasional shooting, it was more about surviving in capricious and mercurial police state.
* Gameplay. No thought given at all. You has rifle, the one same dumb linear location (two, if you count "tutorial"), bunch of random dudes, moving on rails, and pic of dudes who break the dress-code. Thats it. Oh, and it's short, very short. Hell, Tactical Assassin is 10 freaking years old, and still offers better gameplay. You coud have make your game at least slightly better by making more than 5 variations of targets and changing their movement patterns once in while.
* Art. Disproportional bodies, horrendously low level of detail, lots of sharp edges (look at least at that lieutinant's beret, dammit!), and shading was outlawed looong time ago along with facial features and non-acidic colours.
* Other. If I really was such shooter, first guy who I'd shot is that git? who was picking names. Eklat and Kudos, for God-Emperor's sake!
Sorry for occasional errors, English is not my native language.
