About This Game

An idle defense game about mining crystals and defending your wall.

Your base is under siege! As the keeper, you mine crystals while fighting off endless waves of enemies. You'll upgrade your defenses, boost your mining efficiency, and unlock powerful abilities as you see how long you can survive.

Every few waves, pick from three random permanent upgrades that shape your strategy. Will you become an unstoppable warrior who barely needs walls? A mining tycoon with impenetrable automated defenses? Or find your own path to survival?

Can you find the perfect balance between gathering resources and defending your walls?

 

                                       

And of course, don't die...
