This could turn into something more interesting if you added in more mechanics to further the gameplay past "just walk until you find the exit while keeping a loose mental map". Think some elevated spots that let you see a portion of the maze, a thread with a certain length you can arbitrarily use at some point and will signal your path in the ground for a while, see-through walls, stuff like that.
I think multiplayer can be a neat concept too.
Maybe the minotaur shouldn't rush you a lot though, can you escape him at all once he sees you? Maybe some walls the player can go through but the minotaur can't?
Aside from all that, I have to ask you to please remove some of the materials for walls/floors as they really hurt the eyes, heh. I liked the rock bricky wall and some similar ones, but stretched bunch of colors/missing material pink floor/etc are really unusable. A slightly wider FoV wouldn't hurt either.
