AC II: Mobile on steroids, basically (reused assets and all). In that aspect, it's a 10/10.
My only gripe with this game, is that its sound quality ain't as good as II's. Don't know why, but the devs decided to replace the bitcrushed grunts and screams for when both the player and enemies get hurt, with extremely simple midi sounds, making the game sound mighty cheap.

Aside from that, I love it. Played it on a Sony Ericsson W580i back in the day — and along with II and the PoP ports, 'twas the very reason I got into gaming and game development.
