I made the paths thin (1px instead of 4px) to make it easier to see the tree on top of the maze. But to avoid the path/wall ambiguity, maybe it’d be better to start the paths 4px wide, transition to 1px, and then transition to the tree layout…
Your idea sounds fantastic - the problem really was with how I perceived the maze (black paths, white walls)
It would be great if you could add more comments to the code, or a simple separate guide for each of the projects. They are all amazing, and I'm sure many would want to learn more.
I guess making a guide for every Gist Mike posts would be quite demanding regarding his output, in the end even his day only 24 has hours.
