In this puzzle, you must "destroy" every block and item in the room. This means that there are no blocks or items left in the room or your inventory. However, you may not leave the room or let any dropped blocks or items burn, fall in lava, touch the cactus, or despawn in any way, and you may not leave the room. Remember to post a video response of your attempt to solve it!
