Toby: The Secret Mine, is a critically praised video game that has existed on Android for some time. It focuses around a young boy named Toby who lived in a village. When the residents of that village are all kidnapped, he begins an adventure that takes him through many treacherous areas in order to rescue his friends and family. It’s a platformer with a bunch of puzzles that players will have to figure out to advance.
The game has a very elegant art style that, paired with solid platforming gameplay, should make it a pretty good purchase. The game is $4.99 on Google Play and is available on both phones and TVs. Although the Play Store description does not mention cloud save support, it does use Google Play Games for achievements.
