Jump, Fly, Leap:
Keyboard: 'W' 'SpaceBar' and  'Up Arrow Key'
Mouse: Left Mouse Button

City & Pond Levels you are only able to jump again once you have touched the floor.

For the Forest Level the more you Press 'UP' the higher you go.

Only when flying in the Forest Level you must not stop flapping your wings or the little Owl will lose the height it needs and will fall and well the game will be over...
