Tiny Thief, developed by Barcelona indie studio 5 Ants and published under the Rovio Stars umbrella, does have a little bit of stealth, but it's more point-and-click adventure than full-time sneak-'em-up. Whenever thievery is the focus of a game, it's natural to assume that the result will fall into the stealth genre.
