I completed it with all glowing frames this morning. Level 81 with a silly score of 243, 079, 530. It gets a bit too easy towards the end. Which is an odd way for a game to work. Anyway, I enjoyed it.
Are you going for all the hidden levels too? A lot of my points were gained by doing the same levels over and again until I got all the glowing frames.
Put all your skill points into more manner per kill, when its full go for increased starter gems, don't mix gem colours when combining them, keep clicking the speed up button but keep an eye on whats coming up and lay off the clicks if anything with a speed over 3 comes up.
