Yes I have

Now to try survival sandbox

You got it right, survival is endless, have you beaten extreme yet? survival + sandbox mode = some high points!

In survivor mode does it mean that there is no end? I got to level 55 (2 million points) I was going to do a screenshot when I saw I was going to lose, but got sidetracked while I waited for my graphics program to open and accidently copied something else, losing my SS So was I close to finishing or is there no finish to be had in that level?

my bad i realized my mistake after posting but didn't go back and fix it

I forgot there was a gem called a diamond, when i said perfect diamond i was referring to shape, i just meant perfect gem lol

if you get two of the same perfects at a time you can combine them into an uber..... USUALLY only happens in sandbox mode when you have the money to repick gems a LOT but i did get it once in a regular game.... forgot to save screenshot =(

I've gotten a few perfects, but never a diamond. I've gotten amethyst, emerald and sapphire. (not in the same game, though)

I like that map, I'm going to have to give that one a try. I'm working the extreme one now, finally beat normal and hard.
