I think Bombman is meant to represent Chica in how him holding is bomb is like chica with her cupcake Quickman is foxy cuz fast I think Hardman is meant to be Bonnie but I don't see any real connection Concrete Man is Freddy cuz they're both kinda stocky and brown
The only reason I’m convinced this is a Make a Good Mega Man Level 3 level and not a heavily modded Mega Man Maker level is because Volt Man actually has a line of dialogue.
Going through my first play through of this level, I noticed all the split paths I was missing and it raised enough flags for me to just use the skip teleporter after I finished the level to collect everything else.
