I've posted a new DK2 compatible version of the Crashed Lander demo. I've had generally positive feedback on the 0.4.1 SDK versions of the full game so I decided it was a good time to update the demo. Both the demo and the full game are now using the 0.4.2 SDK.
The demo is available for Windows and OSX and includes 6 full levels from the main game. Grab it here: http://don-whitaker.itch.io/crashedlander. You can also still get the standard 'monitor' version of the demo. (^_^)
