The game is in Beta- version, so I need some testers. I could not find any errors, and that is strange

The game should work on any QL and only needs Toolkit2
ORIGIN
===============
The oldest version of this game that I was able to find is one written by HpDUSS
for the HP-48 calculator, dated October 10, 1995 and it was called DStar.
It has since been ported to various other systems, including various Texas
Instruments calculators, Atari, ZX Spectrum, TS2068, MSX, Spectravideo and
even Android and Apple devices.
SCOPE
===============
The scope of the game is to collect all diamonds in the least possible moves.
This is not simple by any means and will require quite a bit of thinking
and planning.
