Cavern Drake 1.5.0 Update Now Available. This update addresses many bug fixes, provides two more FREE characters, makes a couple of the premium items available for free, and best of all, makes gameplay more fun by switching to 100% tilt-based movement, unlimited firing (as fast as you can tap!), and more.
So if you already have Cavern Drake, please update immediately! Otherwise, you can download it for free from the App Store →
