Before I report a problem let me say that this is probably the most addictive game I have ever played and that includes Elite. I love it. I would also love a save game option.
Anyway I had just won on level 22 and got the congratulatory message. I clicked on OK and bang 'Eufloria has stopped working' When I went back in, level 22 was not shown as completed.
Thank you in advance for any attention this question gets.
