Mega Man 2
Mega Man 3 (both via Mega Man Legacy Collection, Steam)

These are both definitely stronger games than MM1, not to mention feeling much more fair (with a few exceptions). I used rewind/save states significantly less here but I'm still not enough of a Mega Man fan to try to do everything clean.

I think MM2 is the stand-out so far, despite being mostly pretty easy. It has the best set of Robot Masters so far and the best set of powers. I liked MM3 significantly less in this regard, though that game is much better in terms of movement options thanks to the slide and Rush. MM3 is also way way harder, even more so than MM1 despite the difficulty feeling fairer. I dunno, they're both pretty solid!
