I already started trying to code something similar, and I think I know how to make the teleportation thing but I have absolutely no idea of how you did the many reflections thing that you can see in "The Tower". That really blew my mind. I mean, when you look at a door, you see what's in front of the other door. I mean, again, in the tower, instead of seeing a wall, you see what's in front of the exit door in the next floor. You'r game did that in a great way, so much that it feels real.
Gosh I have so many ideas!
And thank you for those recomendations! I really love these kinds of visual games, where you need to see the world in a different way in order for you to finnish them. I also recomend you the https://xra.itch.io/memory-of-a-broken-dimension game, which is really interesting and has a very cool dark ambience. And also try https://ianmaclarty.itch.io/forests-are-for-trees . All of his games are really strange optical illusion things.
