Anyway, to me, the game isn't all that hard and the boss is a proper boss where it tests all you learnt throughout playing the game. Such as the fact that not wielding any weapons lets you move faster! There is only 3 enemy types though besides the boss, who are all pretty easy to deal with, even in small groups. Ranged or enemies with different mechanics would've been nice!
All in all... it is free so there is no harm in anyone playing it! Well worth its playtime too!
