Back before he invented Minecraft, developer Notch made a little Java game called Miners 4K, which had you digging tunnels on a 2D playing field for little miners to find minerals and other goodies below the dirt. Another developer named Jean-Philippe Sarda later decided to take that idea and run with it on Apple's iOS platform, and the result is this game, Micro Miners, out this week on the App Store.
You can see the basic gameplay idea in the video below: The game's sort of like Lemmings, in that you guide the path of a bunch of little creatures without actually controlling them. Instead, like Where's My Water, you swipe across the screen to dig down into dirt, trying to guide them around obstacles to various deposits and other goodies. The action can be relaxing or frantic, depending on where you are in each level, and while the graphics are definitely not extremely polished, they're well-designed in that it's always very clear what's happening in the game.
Micro Miners is a smart and fun take on Notch's original title, and for just US$0.99 in the App Store, it's definitely worth playing. Give it a look if the video below interests you.
