Build and Shoot

Ghost trick
It's amazing. It has the best storyline I have ever seen on iOS.
The animations are smooth, albiet a little pixelated.
It's however quite wordy, and the gameplay is average.
The first 3 chapters are free, so get it and if you get hooked in those 3 chapters, I would pay the hefty fee to get the next 17.

I advise getting Trigger Fist for a great shooter experience.
It's a great game, runs smooth, and is most importantly, fun!
