The new version features new audio for both the menus and when completing a puzzle, which is looping in a more smooth way, and breaks the monotony it had before.
Also the Linux builds now include all dependencies, so users should be able to just download and play without much hassle.
The demo versions are available on this site.
Windows: Indiedb.com
