Thank you for recording the video. I was pleased to see that someone finally tried to complete this game.
You were very close to completing the game, but it seems that some of my “solutions” were not entirely clear, such as “jam the stapler into the vending machine,” because it is not a task, but a hint. You only need to complete the 4 tasks marked with numbers (tasks 1, 2, 3, 4) and nothing more. Only then can you exit with the key. However, this is definitely not your fault, but mine, because I didn't make the game more understandable
