Have a perm power up at the end of a level and you can stack em. For example go and make it after you beat the first level you get a double jump. then you can get left and right lunge after you beat the beach level. then it would also be cool to get a "float" effect after you beat the third level and the main idea is that after you get all of these you can use em in tandem with the extra movement speed to "skate" through a level faster and make it more rewarding to replay content. this is kind of reminiscent of mega man x and also destiny 2 skating as it is kind of a similar concept.
