Magical doors/shortcuts between the rooms?

More elevations and "pendences" ?

Some rooms can be really sneaky with vegetation as well. as I think the water sources might create dangerous musk and growing branches, hard to cross.
I also think you can try to test different textures with the floor.. to indicare different difficulties.

Some can bemore dry, some really rocky, some "marshy" and some really sloopy, as mud.

That's a first impression.
