Okay, Quick Man, Wood Man, Metal Man, and Bubble Man have all bit the dust.
I remembered that I could use the self-made platform to retrieve the extra life at the start of Quick Man's stage, and I did that - in fact, on the successful try, I think I was able to retrieve all three extra lives in the stage. I immediately recognized the lasers from I Wanna Be the Guy, but all the rote memorization needed was a little agonizing. I think I felled Quick Man using Crash Man's shell bombs. At one point I used Time Stop and noticed that Quick Man took a lot of damage from that, but after it failed to do any damage several times, I deduced that it was because I had carefully timed the Time Stop to coincide with Quick Man getting attacked.
Wood Man's robotic forest was far more about the enemies that the platforming. Yesterday I was thinking "WHOA" when I saw the giant fire-breathing robot dogs, and as for Wood Man himself, I could never figure out what to do against him until I found out how TERRIBLE he is at dealing with Crash Man's bombs. Four down, four more to go.
Metal Man's stage was full of conveyor belts and gears, kinda like Final Egg in Sonic Adventure. I remember getting an extra energy tank only to realize that I had screwed myself, but ultimately I kept both intact for the rest of the stage.
This time in Bubble Man's stage, I completely avoided getting hit by the one-hit KO spikes. I think I got to Bubble Man without dying, and then found out that Metal Man's gears are so powerful once I was right on the verge of dying.
This leaves Air Man and Heat Man, to stages full of perilous platforming that requires rote memorization. Joy. Actually, that likely wasn't so sarcastic!
