A downloadable prototype for Windows, macOS, and Linux

This is the pre-alpha prototype build of King under the Mountain to co-incide with our Kickstarter campaign - kickstarter.com/projects/rocketjumptechnology/king-under-the-mountain

Please note this is very early in development so most features are missing - we would definitely *not* call it a complete game at this point. However it should give a good impression of where we're going, and more importantly, prove the game actually exists and is something we're capable of developing :)

Currently this build supports English, German, Spanish, French, Italian, Danish, Norwegian, Swedish, Finnish, Russian, Polish, Hungarian and Portuguese.

Install instructions

Windows - Just unzip somewhere and run the King under the Mountain.exe, as long as you're on a 64-bit version of Windows it should work! If not, please let me know.

Mac - Similarly the app should run on any modern version of Mac OS (if not please let us know!), just unzip and run.

Alternatively you can install the Java 8 runtime and click the "undermount-desktop.jar" to launch the game (which should also work on Linux distributions).
