The Spring Thing version was a bit rushed, but I'm glad I took time to iron out bugs and add new features for release 2. I hope you are too! The puzzles are unchanged, except for the final ones, but it should be quicker and more user friendly, and with more silly random jokes.
You can grab the ZIP file with the binary and supplemental materials at https://github.com/andrewschultz/fourdiopolis/releases/tag/v2. Thanks to Zarf for the python regression testing scripts that helped me test a lot of things that'd have been nagging otherwise. I think/hope it was good enough I won't strictly need a release 3, although there's always room for tweaks.
