Monument Valley is another reminder that a game doesn't have to be long to be worth the ride. At this moment, it's discounted to just 99 cents on the Amazon Appstore, a discount of 75%. I've expressed my fondness for this game before, so I don't need to ramble on too much here when I tell you that, assuming you can put up with having Amazon as the distributor, this is a deal that you're going to want to jump on if you have yet to put the immersive puzzler through its paces.
The Amazing Spider-Man 2 is also on sale for the same price (though it's discounted from a significantly higher $6.99). It's a Gameloft title, so I'm going to ask the gaming elitists among us to refrain from looking down upon the plebeians who may be more attracted to this title than Monument Valley. Marvel is big these days, and we're not here to judge.
