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.

This is pretty cool. I'm not really into this, but it reminds me of the old days of watching the windows screensaver. Not really sure what the point of the hammer is as it doesn't seem to let you make an informed decision on what's behind the wall. It might be neat if you could get some semiaerial views from a corner. Keep up the good progress!
