Very nice... a few suggestions:<p>- When you click a constellation and win a chance, unless you match a group of 4+ on the same move that chance is used up immediately. Perhaps it would be more intuitive to have it as a free move?<p>- For chances remaining, when it shows 1 and you use it up it's game over. I was expecting that when you use your last one up, you have 0 chances remaining after which missing a group of 4+ is game over.<p>- As others have mentioned, sound effects would do wonders... increasing in pitch as the chain number increases, just like Beflowered, er... Bejeweled does it. :)<p>- Consider adding a timed mode to increase the pace and excitement.<p>Again, great work. It looks and plays incredibly well!
