Hop in your driller and reach the center of this strange alien planet in Reach the Core. Use the arrow keys or W and D to turn your drill. Harvest minerals to purchase upgrades and unlock new drill equipment in the shop. Spend wisely!

You might see import and export buttons on the main screen. This allows you to "save" your game and move it to a different computer or back it up, in case someone clears your cache on your computer. Just hit the "export" button, paste it into a text document (like Notepad or Microsoft Word). Then, to load your backup, copy the text you saved to your keyboard and hit the "Import" button. Then paste your text into the white box (hold Ctrl and press V), and press "Load".
