I have noticed that nobody has beaten my boss "The Mage". And only one person has entered his second phase. That's all out of 12 players that played my game.

And because of this I wonder, what can I do to motivate my players to defeat this boss? Do you know any good practices for that?

Okey, I get it. I am not qualified for the leaderboard, but can't you at least show me what were the average ratings. Like why wouldn't you?
