This is a simple android input keyboard designed to make it easier to play the original Civilization game in an emulator such as DOSBox. It puts the most common controls (the arrows plus diagonals, and the various keys used for various actions in the game) on a single pane.
This app is ONLY the keyboard, and does not include the core game or the emulator. It is probably not useful for anyone other than people trying to play this particular game in an emulator.
Once you install it, you can select this keyboard from your device's input settings menu when you play the game.
The keyboard itself is admittedly a bit awkward beyond basic use in the game. The main game features are on the primary keyboard pane, and you can toggle between numbers and normal letters using the shift key in the lower-left.
