It's more classic Mega Man alright, but with a twist. The Double Gear System; Speed and Power. Both are really nice additions to the series but I'd say the level design tends to use them as much as possible. Speed is most effective for levels and platforming and Power for bosses to deal more damage per second. Don't try to force your way to the end without this Gear System, it can range from being the easiest Mega Man ever to the hardest one, if you don't use it.
Boss Weapons are really useful tools not just to hit bosses weaknesses but throghout the levels. The enemies are mostly in spots that are hard to reach with the normal buster. Being able to instantly change weapons with a button is also great, that feature is carried from Mega Man 9 and 10 so playing with Boss Weapons on levels is as fun as it should've been on the NES titles.
It's a decent game overall. I also do like the amount of effort that went into the presentation in this one, looks really good. But ultimately I didn't feel anything by the end, specially knowing Capcom hasn't released anything Classic Mega Man related since this game hit the shelves in 2018. I could consider it a wasted effort on Capcom's part for not following the momentum Mega Man 11 gathered for the classic fans like myself, perphaps. It came and went like the wind.
I believe the classic formula hasn't evolved since the NES era, for the bad. It doesn't hit that charm past games had even with a modern coat of paint unless you truly want to be a tribute for the classic like Inti Creates did for Mega Man 9 and Mega Man 10. But it's just that, a throwback to simpler times.
Mega Man needs to evolve, in general. And have a modern standard beyond what the classics offered.
