Cool game, and cool concept! I like how you've added the premise - I play as either a Minotaur, or the Spartans; it's no longer just a maze game.
It might be worth to add some in game explanations. Despite the fact, that I still play Age of Empires, I didn't realize the controls from there, apply here as well. (Even AoE was telling the player to "click the soldier, then RIGHT-click near the flag")
Add the audio! The game experience will immediately improve many times over!
It's true, that the Minotaur from Spartan mode needs an AI improvement. On my first try, I didn't meet him at all. On my second try, it just rushed full kamikaze at the Spartans, and died in the light, since I had them stick together.
So, overall, enjoyable game, and some meaningful progress made over this month!
