This one is really good. Probably the best of the Gameboy Mega Mans. IV and V are really good, but I think V is very slightly better. I love the theming on everything. The celestial theme and the Mega Arm really make this one stick out against all the other Mega Mans in my mind. I think Tango is dumb though. I like all the weapons, though I did think the block picking up one was pretty useless, same with the dash due to the lack of screen real estate. The bosses were super fun. I really like the Mega Punch, I think its fun to use and it makes me use the other weapons more since its not as spammable as the charge shot. The music is great and the stages all look great too. The game just has a nice flow to it. I think it falls off a bit in the final act. I did not like the space shooter section with rush. The boss rush with the Mega Man Killers was a nice novelty, but it all being in one level kind of sucks. I really love the final boss though. The fact that most of the weapons, aside from Tango, the dash, and the block picker upper, were useful made it a lot of fun to navigate through the levels. The levels never felt like they overstayed their welcome, and aside from a few moments where they just drop you in a pit and expect you to dodge spikes, felt extremely fair. They're challenging and just fun. I felt great while playing this one. I'm glad I gave the Gameboy games a shot. This, IV, and the first one to an extent, made it worth it.
