-Figure out what each world can do. Even jumping off the edge in Level 4.
– The only controls you have to work with are the directional keys so experiment with them (holding them down, jumping a lot, etc.). Sometimes the best way to see what ability a world gives you is to go to another world and bring it with you (since some of the worlds are flat and/or don’t allow you to fall to your death, this prevents you from finding out the world’s ability).
– For some reason, the W key will work in activating an ability when the up arrow does not. Possibly an oversight on the developer’s part. Keep this in mind.
– You will have to switch between the abilities in mid-air to complete some of the puzzles.
