Dragon Hills 9+

I like it. It is much better than CATS. I will play it again, and again. (Who knows the reference?)
This is a lot of fun once you get into it. It isn't the best game in the world but it's great for what it is. My only concern is the lag when there is a lot of action on the screen.
UPDATE: This game gets better and better. I play it more than any other game now. I have most of the "power ups" and am on level 63. I hope there is no limit to the levels (unless there's a true ending). Please add more weapons/power ups/dragons/etc. Soon I will have everything and not much to strive for anymore.
UPDATE: absolutely love this game. *DEVELOPERS*I am on level 126 and have all of the power ups maxed out. PLEASE ADD MORE STUFF QUICK!!!!!

And then this.

I was looking for a game that taught something valuable to my child and wasn't presented in an educational framework - something like the games I used to play as a kid, but simple enough for a four-year old to operate. I found this game months ago and both of us can't get enough.

Dragon Hills teaches hand-eye coordination in a unique way, and its one-touch operation couldn't be simpler. Just when you think it's getting repetitive, you'll discover nuances in the gameplay. If you get "addicted" to games, you better steer clear of this bit.

This is not to mention the graphic and audio mastery. We play on a UE Boom 2 Bluetooth speaker and it sounds more like action scenes from Pirates of the Caribbean than an iPad app. Animations are on point. Storyline is appropriately simple and still fresh.

Only drawback is a slowdown in gameplay when sprites max out, even on my iPhone 6s (newest processor at the time of review).
