Thanks for the review !
It was one of the objectives of having a troubling world that the player had to wonder around to understand the link between the vases, I structured the world in a way that if you take the open doors in the order you encounter them going to the right (well, in a cylindrical world you can go the other way anyway xD), you found a closed door, and you have to backtrack to found the according lever, also you can at the beginning go to the last level (the altar) but it will not be unlocked until you use the final lever.
But indeed more work could've been done for clarification on how the doors/levers are linked (and I kinda screw some numbers so it adds to the confusion xD), we'll try to arrange the first levels to add more clarity, I'm happy that you still were able to appreciate this world !
