I thought this was a great game! It's mostly because the premise is so simple, but you can do so much with it! I didn't even know how I was supposed to advance at first. I thought the jewels that were encased in stone were just things you couldn't use. I should have looked harder.
I love the music. The most I ever got in terms of a combo was ten times. It seemed like I had more than that. Maybe when I get there, it just doesn't show up? I was amazed at how long I was able to keep up with a level before beating it.
