Not sure if these numbers correlated directly with C2's velocity numbers etc, but i thought it was neat so i'm posting it here.

Its a HTML5 based interactive jump calculator, which allows you to tweak the height/speed/distance of a character's jumping ability.
It lets you know the various speeds etc down below
eg:
// Values are in pixels per second (velocity)
// and pixels per second squared (acceleration).
const MOVEMENT_SPEED = 586.00;
const INITIAL_VELOCITY = 2201.61;
const GRAVITY_RISING = -12057.40;
const GRAVITY_FALLING = -5070.53;
Are the numbers for the platform behavior based in pixels per second in C2?
Haven't tested it myself yet....
