Ok, got it from "repository.maemo.org bora free" by installing tuxpaint from there. For some reason i wasn't offered to install the lib seperately, but i already knew that tuxpaint relied on it as well and i found that tuxpaint was installable.

The game is running fine. Now it's time to think about a port of my tilt dongle (http://www.harbaum.org/till/palm/adxl202)

Thanks again!

BTW: Would you mind putting the source code online as well?
