This hack changes the stages to be mostly based on stages from MM1 (except for Air Man and Flash Man’s stages that are based on Wily 1 and 3 from MM3 respectively but that is to be expected), but it also ports over the music from MM1 and also gives the stages new palettes so it’s actually a bit more interesting then what you might expect.

The levels are very well designed and provide a reasonable amount of difficultly, and aren’t too unfair. The level design was quite interesting as well as creative in some areas such as the Item 1-3 puzzles in Wily 1 and the entirety of Crash Man’s stage. Although, Air Man and Flash Man’s stages might just be my favorite stages in the game, as the level design in them are really interesting mashups of the original MM3 stages that they’re based on as well as MM2 Wily 1 and 4.

Since this hack mainly uses MM1 aesthetics, the graphics aren’t too mind-blowing, although, the new palettes do look really good (the new aesthetic changes as well like Cut Man’s tileset being changed to take place at night and the rain in Wily 2 were nice touches), and I also like how Guts Man replaces some of the Changkey Makers.

The music is also ripped straight from MM1, which again it isn’t that exciting, although one thing I found odd about the music choices is how the normal boss theme isn’t used until the boss rush while the fortress boss theme is used in the first fights against them… for some bizarre reason.

Aside from Flash Man, the Boss AI hasn’t changed much aside from weaknesses, although Air Man’s tornadoes now do 8 damage which makes the fight a bit unfair now since the tornado patterns that are nearly impossible to do without taking damage haven’t been updated. The weapons have also not been changed aside from weapon energy consumption.

So, overall, I’d recommend this to people looking for a good challenge (just make sure to play the original version, the Wily stages in the plus version are pretty brutal).
