A fun little endless runner Pac-Man game from the creators of Crossy Road. Available for both iOS and Android. Free(mium).
This game has so many neat little touches. The way the camera zooms in when you're about to eat a ghost, the way that Pac Man's "wakkawakkawakka" speeds up as he gets closer to a 256 pellet combo, the little wave distortion effect when you die. It's all very nicely done.
It's also really slick being able to switch between portrait and landscape in the middle of a game; I know how hard it can be to implement that in a UIKit app, so I'd imagine that it was something that they spent considerable development time on.
