Jump - goes off of which direction Yooka is moving, not how long they were moving in that direction. Not yet known if it uses neutral vs forward jumps or if you can move as freely in the air regardless of how you took off. BK had modifiable neutral jumps, for reference.
Flutter - usable after a jump, cancellable early. Longest seen duration is 3 seconds. First three seconds of arc seem to be two seconds of almost no altitutde loss, then one second of a 45 degree decline. Not yet known if there's a maximum duration or the full arc.
Roll - travels quickly. Not yet known if it requires a stationary start like Talon Trot, or if it can be activated while moving. Not yet known how it interacts with walls.
Grapple tongue - used by Yooka. No footage seen yet.
Sonar blast - used by Laylee. No footage seen yet.
