I tried to play your game on my linux machine but I got this error when I execute it:
X Error of failed request: BadLength (poly request too large or internal Xlib length error)
Major opcode of failed request: 18 (X_ChangeProperty)
Serial number of failed request: 244
Current serial number in output stream: 244
It worked before but stopped since version 0.7. Also tried on another linux machine but still get this error.
