I don't really know what to say, so I'll just go through my gameplay experience.
In my first playthrough of 8 minutes of walking around, the first place I found had ammo and a radio. Then I followed the road for several minutes (Because all roads lead to somewhere), but that lead to an invisible wall. The next place I found apparently had a land mine that killed me and ended the game.
Second playthrough I found a campfire with ammo, a spot with landmines, then the same place where I died the first time, which was a spot with only land mines, then I ended up at the radio spot in my first playthrough, then ended up walking into an invisible wall. After 15 minutes, I somehow ended up back at the starting location. After about 19 minutes into the run, I found a tent with a land mine, rifle and cross. I could only pick the cross up, but I don't know what use it has. After 22 minutes, I stumbled upon the place with the radio again. After taking a closer look, I found Kinin on the ground next to it, almost blending in with the surroundings. Guess I missed it the first time...
Since I roughly knew where I was now, I headed back to the box at the spawning point with Kinin and cleared the game. This run took about 25 minutes or so.
The sprint is about 7 seconds of slightly faster walking. The screenshots showed a threat, but I found nothing during either of my playthroughs, so I never had to use the gun.
This game has potential as a horror game. But as it is right now, it's more of an uneventful walking simulator with no story.
