Lunar Lander

Eventually...

The world is simulated in Javascript (TODO). The lander controls are handled by a UXN emulator (TODO). You can tweak the uxntal code, rebuild it, and run it (mostly TODO).

The Infrastructure

I'm relying on the uxn5 emulator by Devine Lu Linvega for the UXN and Varvara emulation. I'm also using the drifloon (part of the drifblim project) assembler, also by Devine Lu Linvega to actually turn the uxntal code into a rom for the VM to run.
