Touch Arcade - How long do you need to play to have a good time? Windosill [$2.99] is a straight up terrible value proposition if you like serious length from your games. It doesn't take much longer than 15 minutes to run through and there's no real replayability. But damned if it isn't a great 15 minutes while it lasts.
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.
