Everything that once was non-mobile is now mobile. So spake the prophets thousands of days ago when the mobile world became a "thing". A couple of really great games have made the crucial crossover recently, and we're here to swoop down and play them.
Free game: Space is Key - Alternate title: Space is Key is Free! Until July 3rd, that is. With Space is Key, you control a sliding cube that moves from left to right, right to left, then left to right again. Head through each section of the grouped levels and tap the screen to jump, timing your moves just right to clear the obstacles in your way. Grab the star to proceed to the next area, and nab the shiny cubes to activate/deactivate parts of the environment (or, you know, don't touch them because they'll destroy you). In addition to its freeness, the game has also been released for Android and Kindle Fire, and the iOS download is now a universal app! (Space is Key review and download links.)
iOSified: Anodyne Mobile - We loved, loved, loved Anodyne when it was released for PC/Mac/Linux in February. It's one of the best, most emotionally stirring and beautiful RPGs since Earthbound, and that's saying a lot. Sean Hogan and Jonathan Kittaka have just released an iOS version of Anodyne that ports everything over to the touch screen world. The controls are virtual, of course, which is a bit of a downside, but otherwise it's a flawless experience and an easy excuse to play the game all over again. (Anodyne review and download links.)
Now mobile: Tribloos 2 - The creative sidescrolling time management building game from Bumpkin Brothers The Tribloos 2 is now on iPad and Android! As the benevolent administrator it's your job to organize the tribloos to distribute labor as efficiently as possible. You do this by assigning workers to gather resources, remove obstacles, rebuild houses, sawmills and other structures, and staff these locations to keep the resources rolling in. Its touch screen counterpart has been reworked a bit to make tap controls easier, but the underlying game is just as satisfying and addictive as ever. (Tribloos 2 review and download links.)
Androidified: Factory Balls - Bart Bonte's unusually addictive puzzle game Factory Balls made the jump from browser to iOS back in May. Now Android owners can enjoy the uncannily entertaining puzzle game! The idea behind Factory Balls is you need to alter a blank sphere to match the image marked on the box. Surrounding the center are various colors of paint, seeds, watering cans, belts, hats, glasses, tools, and other items, all ready to take part in your quest to get this thing decorated.
