Lighting Piece

игра прикольная красивый графон.А делал это один человек или нет?

It's in Russian????

The game is good. 
I do appreciate the solo work and not using pre-made assets for the game, it's rare to see games with originality and dedication to it's own work, although, the game has lot's of issues. 

Well, first of all, FPS and sensitivity needs to be fixed. It's very difficult to shoot and move around with both the gun and the flashlight too, maybe fix that. I encountered 2 major bugs, one was in the ventilation system, when I passed a certain point, it would not make me go back, even thou I was crouching. The other one was with the monster, they showed up, I started shooting and then some crystals appeared and blocked the door. 

Now, the checkpoint and restart system - this game needs it really bad. I can't get stuck in one place and then close the game and open it every time this happens. Restart system is not hard to do, so definitely should work on that. 

Now, overall, the game is not bad. I would recommend adding some information about the whereabouts of the character we are playing, some notes, maybe voice over, but notes would be easier to do, in my opinion.

For the game to be at least playable and enjoyable, you would probably need more then 1 month to finish, at least one month can be for the actually demo, legit one, because this is just a playtest version. 

Good Luck with the project. 

Edit: I forgot to say, the language barrier - you should consider adding English subtitles or if you can translate the game. For me it was easy, because I do speak 5 languages and one of them is Russian, so I got the controls and everything, but for the majority, the translation is necessary, unless you don't want your game to be played by others.
