The game's called Windosill, and it's utterly lovely. It is a wonderful and clever puzzle game with insane amounts of care and charm pouring out of every orifice. Yes, every orifice.
Hardcore Gamer: This week's Humble Weekly sale features a handful of offerings from Amanita Design, and other devs. you can pay what you want for Samorost 2, Machinarium, Lume, and Windosill. All but Windosill come with OSTs. Paying more than $6 gets you Shelter and its Circle Storybook, as well as Botanicula and its artbook and maps alongside OSTs for each.
John of GAMElitist.com - "There is one new caveat, though. The Humble Bundle guys had a problem with illegitimate Steam accounts before, which raised the price to $1 minimum if you wanted to get Steam keys. Well now, the minimum price to get Steam keys for this bundle has been raised to $5. This shouldn’t be a deal breaker but be wary if you want to add these games to your Steam library."
STP: Windosill will only take new players around 45 minutes to complete, but every second is superb.
