Big new feature on puzz.link: You can now solve puzzles together. Just start network play via “File -> Network play” and share the link. It’s quite experimental and likely flaky, but already so much fun that I decided to share it now.
Otherwise, there’s been countless changes since the last update, which I’ve wrapped up in version 0.13.0. Besides various bugfixes and improvements (see the full Changelog), we have a couple of new puzzle types: Araf, Balance Loop, Doppelblock, Maxi Loop, Mid-loop and Simple Loop.
