Overall I like the gameplay and it was fun to play, great job :)
I had just one issue in the settings menu, I used to see some arrow or button to return to the main menu, and it took me a few seconds to try the ESC button to go back to the main menu.
Not sure if you should add hints but probably some people will want hints ( I saw in many other games that you have this option) when they were trying to solve the problem for 20 minutes (the last lever took me that much haha)Thank you for the reply.
I thought that if I rotate the boxes (or at least try to), it alone will affect the rates of foreshortening, and that was my mistake.
I didn't realize that the fact, that when I am choosing about the same distance for my vanishing point makes it looks the same.
Thank you, now it is more clear to me.
