An Escape of Many Dimensions

This game was created in a day for the Clicker Jam Spring 2023 (theme: another direction).  This short game is set in the two-dimensional realm of 1884's Flatland: A Romance of Many Dimensions by Edwin A. Abbott.  What happened to our Flatlander protagonist after he got locked away for daring to speak of the third dimension?

This game is played entirely through the use of the left mouse button.
