I don’t have a theme. I don’t generally draw cartoons or pictures with my mazes. Can just plain mazes be a thing, like adult coloring books? There are a ton of neat maze creators that I follow on Instagram or Twitter or wherever. Mine are probably the most boring. Someone used to solve them by blacking in everything from the dead ends back to an open end, leaving only the “good” path open. That seems like it would be relaxing.
