A true hidden gem
The game, made by the same folks behind diner dash, is a tiny "home made" adventure game. The game itself doesn't present many challenges, it seems to be for kids, it's obviously shorter than a "full" game, but it's concept truly makes this game shine. Therefore it's better to see this as an interactive story rather than a true "game".
It's a noir-style detective mystery story taking place in L. Frank Baum's world of Oz, more specifically the Emerald City 20 years after the original books. It's really what you'd expect.
Naturally you'll come across plenty of reimagined noir-styled characters and locations from the books.
So instead of watching a movie, spend an evening or two playing this.
