Alex has updated his game PuzzleManiak with a bunch of themes.

Release notes:

Due to the growing number of available themes I’ve packaged PuzzleManiak 3.5 with only the best themes.
This package is available in 2 format : rar (2,9 Mo) or 7z (1,2 Mo).
And in addition you can still download all themes.
