Connection is broken

I had only a few telephone booths, standing alone in the desert under heavy rain. If I dial the correct number, then I will be able to move ... somewhere else. But what are these numbers? Where to get them? And why is it needed? Doesn't matter. I must go ahead. The main thing is not to be afraid of anything. After all, if I die, I'll come back here.
Welcome to a weird, surreal dream world where our hero must solve puzzles to move on. Having solved the puzzle in the location, you will find out a phone number that will advance you to the next level. Phone booths in the game used as teleporters, and can also change the world around. If you die for some reason, you will be in desert again. However, once you have the right numbers, you can always return to later levels.
The game has two endings.
