Lumino CityI don't know how I missed this when it first came out, but I did.
Lumino City is an adventure game, with the backgrounds and NPC's actual miniatures filmed in the tilt-shift style. It's staggeringly beautiful and entirely endearing.
I don't even like adventure games, really, but I'm playing this game quite often in 20-30 minute bursts. The puzzles are clever, the help system is the best I've ever seen in an adventure game, and it's one of the most charming game worlds I've ever seen.
