Most of the game was finished except for certain music tracks (which is why the the boss intro and Wily Tower level transition use the original ost) and the final boss, as such you only fight the first phase
Honesty really frustrated that this was never finished, i think this was basically a proof of concept in hindsight now cause there are alot of broken elements and it is kind of unfinished. Feel like it has been rushed to release in 2022 and then not been touched since, mainly cause the creator has been mostly radio silent on this. Or i could just be talking out of my ass idk
"Metallic moron"? Is he Wily or Robotnik? Also, Wily kind of blew it with the design of his robots. Buster Rod G and Hyper Storm H are both on theme with Journey to the West, but then he just randomly threw in a kappa for Mega Water S? Why? Just make him a dragon, or another horse if you wanted to stay on theme! That last boss was kind of lame, honestly. Gamma was a bigger threat than that thing was.
You do realize this based on the Sega Genesis game Mega Man: The Wily Wars, right? It's a "Super Mario All-Stars" of the first 3 MM games but with an added feature, the Wily Tower, which features the 3 mega man killers here.
