Also, I just checked my Youtube channel for the first time in a year. Apparently I have a tip involving E4M6 that I am curious to verify. Apparently it might be the only level where five powerups can be activated at once: Bio-Suit (outside secret), Pentagram (secret), Ring (in water), Quad-Damage (beginning), and 100 Health (beginning).

Now I need to see if any other levels do this...

EDIT: I have found E4M4 to do this as well (he probably plays on a higher difficulty as this only works on Easy).

E4M7 also works (though going from the Biosuit to the Pentagram wastes most of the powerup, it expires almost after picking up the Quad Damage in the Pentagram room.
