Or maybe the map marks which levels you used the Super Guide on, to motivate you to try to beat every level naturally to get some sort of 100% bonus.

Yep. Hopefully if you beat it with the super-guide, a green "L" flag shows up instead of a red "M" flag.

No one will call it "super guide." They'll just call it "using Luigi."

If you beat it with the super guide, it returns you to the start of the level and makes you beat the level. What it does not do is allow you to skip the level, as Nintendo reps have stated dozens of times
