Dwarf Fortitude: Endeavor

This is excellent. Courtesy of the IndieGames blog, Endeavor is an adventure-platformer that tasks you with recovering your tiny dwarf's family inheritance from the comfort of your web browser, except your dwarf's journey goes "a bit wrong" very quickly indeed. The platforming itself is dainty and robust, and the dialogue is adorable, but the real allure is provided by the game's Metroidvania exploration. There's a bit of nonlinearity in here, and the game's finale is affected by your actions, so I'll just give you one piece of advice- be kind, babies, be kind. Now go play. You're looking at a good 45 minutes from start to finish, but (in the manner of most flash games these days) it'll save your progress in your browser's cache if you close the page.
