To use your jetpack on default settings you will need to move your right thumbstick upwards. To dash using your jetpack you need to move your right thumbstick downwards while selecting a direction with your left thumbstick. If you're not selecting a direction on your left thumbstick the dash will go towards the direction you are facing. To glide using your jetpack you will need to spread your arm while in the air. Using your jetpack will consume fuel which replenishes automatically once you stop using the jetpack.
