The latest Humble Bundle for Android has a number of notable titles in it like Monument Valley, Joe Danger, Blek and Tilt to Live 2. As usual with Humble Bundles, this is a pay what you want affair to unlock the first three titles, but you’ll need drop down at least $3.66 (at the time of writing) to unlock all 6 options (with another being added shortly).
Monument Valley and Blek regularly sell for $4 each on both Amazon and Google Play, so this is certainly a good value on top of the fact that a portion of your choosing goes directly to charity (EFF and Worldreader) and the developers. Monument Valley is clearly the standout title here, as it rarely goes on sale and currently sits with a 4.5 star rating from over 71,000 users on Google Play.
Monument Valley is a surreal exploration through fantastical architecture and impossible geometry. Guide the silent princess Ida through mysterious monuments, uncovering hidden paths, unfolding optical illusions and outsmarting the enigmatic Crow People.
