Took me a bit to get the hang of it, but once I did it was pretty fun. The sound effects for matching are a bit too loud, my brother got mad at me cause he could hear them halfway across the house lol.
I think you should stack the effects of the matched gems. It's really hard sometimes to get a match at the end of the color you were going for. Would be nice if you could just focus on matches and then burst every once and a while.
