Gravity - type a number 0-100 to decide the gravity [0 being no gravity and 100 being you can barely jump]
Vulnerability: type a number 0-100 to decide how easily you can get hurt [0 being one hit at full health and 100 being very resistant]
Speed: type a number 1-100 to decide how fast you can go [1 being slow and 100 being flinging every where]
