Thanks, I'd agree with all of that, but then I wrote it so I'm incredibly biased. Sorry about the server issues, Fasthosts had a big outage earlier in the week, most annoying. Take a look in the log folder, your scores may have been written out to a file, I can manually submit them for you if you like. Contact details are on the bitglint.co.uk website. Oh and I love that your son has been playing it over his usual games, that's a result!! :o)
Don't worry about the scores, my son and I will continue playing it regularly. I'll tell you something else that worries me more, and that might be a bug. Yesterday afternoon I finally unlocked all the palettes, I left the last one on (Spectrum dimmed, or something like that). Today I started the game and it's as if my data has been erased: I have all the palettes locked again. Maybe you can figure out the cause. I don't mind getting them again, it can be fun. What worries me is that it keeps happening over and over again.
I have discovered the <Setting Key="Palette" Value="0" /> value in the Settings.xml file, but I have never edited it. I don't know why it is set to zero. Maybe after taking them all, the next time it goes back to zero? Or something like that.
EDIT: Never mind: I noticed that this value is the selected palette, not the unlocked ones.
