Hi,
All I can offer is better adaptation of KSokoban to KDE4 (excluding
images) and better look in bigger screen resolutions (recreating images
in bigger resolutions in povray).
Your email suggests that you do not want to see KSokoban in kde-games.
I ported ksokoban to KDE4 because I use it and due to problems with old
version KSokoban in new Linux distributions porting was neccessary.
I could take care of Magazynier but only for money because I do not use
it and do not need it.
For me KSokoban, especially its graphics is the best from all known
sokoban games.
So please confirm that you are not interested in KSokoban and I will not
bother anymore on this list
