I checked, and it seems to alter to very light blue color, I also check out the small demo (3 levels)
which seems a kinda bit low. I looks really nice, as I love puzzle games.

your welcome, as I originally made as base for later the actual, but low graphic game is also a
nice idea like yours.

Keep up the good work, I hope it become a success (but try to set an option for Window Mode
and Full Screen (as I dont like forced Full Screen).
