Great follow-up to the first Mega Man X, and I don't really have many issues with it. The stages and the Maverick fights are unique and distinctive, and a few of them take advantage of the Super FX Chip well. I don't like the designs of the Mavericks themselves as much as I do X1's, however; they don't pop out the same way and are less memorable for that. The music was really good, in my opinion, but there's one instrument that can be a bit annoying to hear, and if I had to give an obvious immediate example, I'd say listen to the start of Wheel Gator's stage theme. I did get used to it, though, I suppose.
The endgame felt better paced than the first game's and I was surprisingly content about the story's emotional beats towards the ending, since I didn't think I was very invested. The final boss was pretty fun to do, and the first part felt way cooler than X1's. Only two issues here are how it sends you to the first segment of the ending stages if you turn off the game and having to repeat a short part of a level you already beat before the final boss.

Still, I overall really enjoyed it, maybe as much as I did the first game. I'm interested in seeing what a second playthrough of both will change in my opinion.
