I had a really great time playing through this - I played through feeling my way around about three times, then on my fourth try I made a map as I went, and it was fun mapping it all out and seeing what the longer-range puzzles actually were.
( I'd love to feature this in the puzzlescript gallery . The goal of the gallery is to let people both enjoy games, and look at the source code if they want to see how the sausage was made. If you'd like to be featured, either include a source code link on this page and ping me, or you can also create a shareable link via puzzlescript.net and let me know it).
