And on what engine did this application? I first thought that Unity...
The first time I see a game on Unity that has only one * .exe file.
The familiar programmer himself doesn’t know how you did it ... But the detachment of that file in it was the unity files

The question is, how could you cram a game into one file? :)
Aha, I'm glad you asked! It's actually a winrar auto-extractor. It extracts the game files to a hidden folder and launches the exe on completion. I don't like how unity games are always in zip files so that's why I used this. I change the icon of the auto-extractor to that of my game so it looks like the game is an exe when actually it's not. ;)
Here's a blog post on how to do this yourself: http://ludumdare.com/compo/2016/04/21/how-to-make-your-game-into-a-single-exe/
Haha :)
In the first I learned that through the archive (win RAR) you can do *EXE

Here is what else I found now. This is a separate program to do *EXE
But I want to say one thing, a big minus of this ...
The game is buried and at the time of opening it is unpacked in temp (Windows cache), and those who have SSD, then this is a pain for them..
