Good news and bad news, folks. The good news is Tentacles: Enter the Mind, a game that has been on Windows 8.1 for some time is also on Windows Phone. Even better, the game is an Xbox LIVE title with Leaderboards, Achievements, and Highscore. Because the game is a universal app, you also get one of the first instances of cloud saves and being able to continue your game on multiple devices. All of that is filed under 'awesome'.
The bad news is like the Windows 8.1 game, the Windows Phone variant, for some odd reason is region restricted. If we hazard a guess, Press Play and Microsoft are easing out this game to see how all of those cloud saves and newfangled universal features handle in the real world. In addition, they were also likely waiting for the Phone counterpart to launch to 'go big.'
