Technologically speaking, this is probably the most "Mega Man on the Game Boy" yet. It copies 4 bosses from 3 and 4 bosses from 4, but the stage design feels ripped from the NES rather than something made to cater to the Game Boy's smaller screen and processing power. Lag is a common factor here, which sucks when having to work around certain jumps. Some stage gimmicks are pretty bad too, such as any gimmick that involves waiting and instant death (shout out to Dive Man and Dust Man). The weapons aren't too great, despite this game being known for the one that makes the Spark Shock not the worst weapon in the franchise. You'll mostly stick to the Shadow Blades since they're still Metal Blades lite, hell even the new weapon, Punk Crusher, is outclassed by the Shadow Blade. The Charge Shot is also present to invalidate weapons but if you know me and Mega Man you know I'm not a fan of the charge shot.

There's a new midboss who's pretty cool and Punk is a solid fight too so the new stuff is nice. Hell the some tracks like Snake Man sound better coming from the game boy's sound chip than the NES, even if I wish original arrangements were made rather than just porting the NES music.

It's still a bit rough but I'd say this is playable, even if a little redundant these days. I'd still recommend Mega Man 3 and 4 over this, but if you need more to scratch that itch, here you go. If the second half was less bs, I'd say this is the best GB Mega Man so far, but it ties with Dr. Wily's revenge.
