Move the slide to unlock levels in this platform game . You must arrange and rearrange the slides so that the character can recover the key and get to the red door . A slide can be used as many times as needed . The black levels should line up so that the character can travel from one slide to another . Check if the character does not drop the puzzle through openings , but keep in mind that the character can be suspended in freefall while you rearrange the slides . Slides should align correctly, if not the character will not be able to travel from the slide that is occupying . You lose if you try to hang on the door section prematurely .
