So, after the release of the game, I decided to make a patch anyway, in which I will slightly change the puzzle with the code and add some new content.

First. I tried to make the puzzle easier and I hope I succeeded. If not, then I made a text file with the answers, if you are stuck at this moment.

Second .I added collectable objects to the game. Now, if you find them all, then at the last location with a long corridor, you will be able to open the door next to the window.

Third. Behind the door, which was recently mentioned, there is a room with a riddle, after which you can get the ending in a slightly different way.
