Congratulations, you've reached the pinnacle of cleverness! You're now officially an expert in the art of thinking outside the box... or in this case, the rectangle.
Here's a special prize for your achievement: The Infinite Jest, a collection of the most absurd, yet somehow profound, jokes known to humanity.
However, don't get too comfortable, as the next level is always around the corner. To prove your skills, take on the challenge of Level 4: The Height of Insaneness.
Note: Please be aware that Level 4 is not for the faint of heart.
Or of mind.
