This latest update changes the way thrusters function and adds 2 options to game variants to tweak them:
Previously, thruster speed was defined by sprint speed and airborne velocity was also limited to the max sprint speed. Thrust speed can now be set separately from sprint speed and there is no limit to how fast you can move using thrusters. Default thrust speed is equal to gravity, which allows for high jumps and hovering but does not allow the player to gain altitude when falling.
Thrust duration defines how long a player can use the thrusters before they shut off. It defaults to 10 seconds, and the timer is reset only when the player touches the ground. It can now be tweaked with a percentage multiplier, or set to infinity.
Check it out, and feel free to discuss further changes in the forums.
