Needs improvement – Word Avalanche FREE. Review

I enjoy this game, but it needs to be updated so it's easier to play on iPhones. The rocks at times don't fall or don't fall as frequently, so it's cheating your time. For some reason, the button to tap with the words doesn't always take, so you have to keep hitting it, which again counts against you. As I said, I like the game, just needs updating. Thx!
