Don't really get why everyone is complaining about bad controls when you can literally rebind them in the game. Right Shift for start was certainly unintuitive but it doesn't take a genius to try every button on the keyboard. Multiple difficulty settings would always be nice but it's really not too bad in it's default state, honestly still easier than the older megamans. Controls weren't unresponsive in anyway really and no cursed delay or anything like that, would say the slide having a bit more priority over jumping would be nice.
I will say I would like more scenes say with some of the normal enemies, especially since I can one hand it given how few mechanics there are, but overall pretty high quality game besides those issues.
