Level 1: Get the arrow keys to change your xVelocity so the penguin can start sliding around the ice Level 2: Get jumping working so you can avoid the bear! Make sure you add gravity so you come back down! Level 3: Add friction so that the penguin gradually slows down on the ice Level 4: Make it so that the penguin bounces off the edges, flipping its velocity in the other direction!
Learn and practice: - X Velocity - Y Velocity - Gravity - Friction - Bouncing
