It would have been nice if the developer's web site provided the information provided here about compatibility. Failing that, information in the download. As it is, attempting to run this on an incompatible system provides no useful error messages whatsoever. The application simply fails to work properly and logs the worryingly obscure message "How many space machines did you fall out of???" multiple times to the console log. Bizarre.

This is on 10.4.11 (PPC).
