Describe the Bug

The higher the framerate from baseline 60 - the slower the speed of Silver's box-ride, yet stamina consumption rate is still regular, which makes it very hard to pass the first sublevel of Kingdom Valley.

Steps to Reproduce

1. Increase FPS to the value higher that 60
2. Face lower speed on box levitation

Expected Behavior

Box-ride with regular speed
