The HinterLands is a mining game, similar to Terraria or Minecraft, but created specifically for mobile devices. The game is currently in alpha stage, and will continually be updated with additional features.
The short term goals are to include most of the mechanics from similar mining games, to provide the best experience on mobile devices. The long term goals are to add more focus on RPG elements, and to add additional multiplayer game play mods.
The game is being released as an alpha version to try to get feedback on features you want earlier on, based on feedback. (Edit: to do internet multiplayer right now, it's the same as Minecraft: http://ackmi.com/2013/07/how-to-do-mu...)
So please leave a 5 star review, and let me know what you would like to see developed first in the game.
