The classic adventure game Grim Fandango has sauntered onto the App Store, and 148Apps has a review. Long story short, they like it and think you should buy it.
Playing Grim Fandango on a touch screen works reasonably well for the most part. Tapping on interactive elements brings up a small wheel of commands like “pick up” or “look at,” and a contextual button will appear when Manny is holding an item that will let him use it on himself if need be. It’s all classic point-and-click style adventure stuff, and that’s great.
