The game is one of the weakest classic megaman entries by quite a lot, tengu man and clown man have very fun stages and design but beyond those 2 the game falls apart pretty hard.
The difficulty is nothing to write home about as health and weapon refills rain on you with some not-so-clever level design that can feel unfair or plain.
I wouldn't recommend people to play this game if they haven't but I also wouldn't recommend against it, it's just extremely mid.
