this game needs SDL libraries to be installed.
to play type syasoko in console window, or click on /usr/bin/syasoko. the levels that you've completed are stored in /root/.djgames, so deleting that file restarts at beginning level.
N.B. if you remove this with package manager, it leaves an empty directory /usr/local/syasokoban, which i couldn't get the manager to delete...any ideas?
