Ive figured out how to surpass that no-spring glitch! ^^
First, Upload jrose05's Ultra-complete gamedata file onto your computer.
Then, upload that flickiefirer WAD.
After the first act of zone 1, if you got that special zone, you'll have SuperSonic at your disposal. But the second act has an area where you'll never be able to reach because springs wont work. This is where the godcheats come in. Set the gravity to something very low, then jump. You'll be able to float anywhere this way, and you'll never need to use a spring anyway! ^^
