This was nice! I just have some recommendations to make the game better:
-The labyrinth could have some landmarks, like an area with a statue, another with corpses, different wall colors etc... this could help with locating oneself inside the labyrinth, since sometimes it gets too confusing which leads to some frustration.
-The minotaur appears very rarely, and when he does he does not seem like a treath, I recommend making him periodically chase the player and after a while he stops the chase and starts randomly patrolling the area, this could keep him appearing sometimes, but not too much to the point of being repetitive.
-I did not see much of a need for the sword and club apart from the endgame, maybe there could be things you could attack or break on the normal levels, although having the minotaur actually chase you could justify their use.
-Some music could be nice.
And that's all I could think of, with some polish it could be quite fun, and it working on actual hardware is really awesome, congrats!
