I try your software 6 months ago, because i need some easy use and non-X window cdwriter interface.
So, these days, i try the latest versions, it was pretty cool, because many mistakes from first versions were recovered, more powerful and...more and more easy to use, this script software grow up fastly !
This code is pretty cool. There are no more options, no additionnal menus, but this is the only one sokoban clone to give animations in soko's move : it was great. The C code is compact, fast and very nice (good C writer).
I tryed to make a sokoban clone later, and i research all others projects that reached this goal : gSoko is the most impressive versions.
gSokoban is not finished, but give some extra options.
kSokoban didn't give animations, buut all the needed toolbars, menus... load file....
YASC : java imcomplete implementation
other java applet over the net : all RIDICULOUS.
Try gSoko, it's great.
