Boosted Sprint

(there's nothing sonic related about this mod aside from running fast)
This mod changes how the sprint tech works in a few ways.
most important is that sprinting essentially cancels gravity for the duration, allowing the player to run/fly through the air.
Because you can now sprint mid-air and activating sprint nullifies vertical momentum, you can stop yourself from falling easily at any time as long as your energy isn't locked from recent over-use.
Activating sprint gives you an instant dash-like speed boost, so there's little ramp up time to full speed. Of course holding the key down means you keep going.

Jump into the air, double tap a direction key in the same direction you're facing and go zooming away! I still miss the butterfly boost of yore, but this is functional in its place.

Fair warning: this tech is pretty over-powered all things considered.

if you decide you hate this change uninstillation will cause no issues, sprint will simply revert to acting just as it did before.
