Megaman has always been unplayable dogshit for deranged autists.
Pic related is objectively some of the worst game design I have ever seen. It's pure trial and error pattern recognition. It's tedious anti-fun garbage that is completely unpleasant to play and overcome. Even when you complete it successfully you just say "That was not good".

Megaman fucking sucks and deserves to be dead. Be happy you got 3 playable games in the franchise and move on.
