Honest review:
Few bugs and issues, things stop rendering literally 2 meters away and it looks awkward and weird, literally you can walk back and forth in front of something and see it disappear/appear/glitch.
In the garage, you hear the "outside" noise, instead of the "inside" like where the computer is, and if you walk to the sides of the garage a weird white orb may flash you.
The story is a bit...meh, feels rushed/random, the idea/concept is there, but once the boss tells me that there should be no Mark, why am I not instantly calling the police/being careful? I know a random guy just came walking and says he's there to train or whatever, he's lying, and I wait the next customer? What? And fill her pump? Especially after another random guy before Mark asked "are you alone?" and left without pump. Also, as I was outside and I was looking inside, I saw the door open and...he didn't come out? That also was awkward.
And the jumpscare was absolutely random.
With a few bug fixes, improved renderings, improved story and a bit more work it can be a funny, nicely made short horror, for now it's lacking.
