A neat take on the theme although I don't think it comes across super well. I wasn't able to guess what the relation to the theme was until I saw you had answered the question below. I would probably add a note to the game's page saying how it relates to the theme so people know before playing.
The overall aesthetic of the game is great, the graphics and audio compliment each other well. The way that the block that the minotaur could pick up the box that Theseus could only push was a nice touch. The only other feedback I would have is that I locked my game on the second puzzle because I pressed 'E' thinking it would drop the box on the button and instead it trapped me in place with the box on my head. That's something that probably more people would do by habit too. Also the instructions on the game page are incorrect as they say LMB is aim and RMB is throw but for me it was the opposite. (HTML version) Otherwise, really good entry and nicely done!
