This mod allows you to customise the speed of each speed portal. You can fine tune the speed of each portal to your liking, or even randomise the speeds of each portal if you prefer chaos in your life, featuring dedicated minimum and maximum speeds! If you're a psychopath, you can even change speeds for Players 1 AND 2 separately! Or you could just... not do any of this, and disable the entire mod in its settings without having to restart.
