Difficulty level	Tilt left/right (degrees)	Tilt forward/backward (degrees)	Speed (degrees/s)
1	3	2	6.2
2	4.5	3.5	9.2
3	6	5	12.2

7	12	11	24.2

Tilt: The number of degrees by which the platform will tilt to a certain side during a perturbation of the corresponding level. Speed: The maximum speed at which the corresponding platform tilt will be reached
