This is a platformer game. You can use the arrow keys or WASD keys to move. You can use the mouse to aim, then click or press space to shoot a grappling hook. You can swing on the chain, then click or press space again to let go. If you want help, need a hint on beating a level, or just don't feel like playing the game yourself, you can watch a playthrough of it here: https://scratch.mit.edu/discuss/youtube/qds7Z5uE-eA/
