I have developed this in Arch Linux and have done a bit of testing on Debian-based distros.  Currently I have been working on the build system and trying to work out some stuff with portability. I haven't finished fixing those issues yet, but for Arch Linux users I did manage to get a lot done! 

The game is free as in libre and free as in gratis. Here is the source code

https://codeberg.org/FroggyGreen/aum

and Arch package repo

https://codeberg.org/FroggyGreen/aum-pkg-arch_linux_x86_64

All the build dependencies can be found there. There are also some runtime dependencies, but I don't have everything sorted out yet. I do know that if you have the build dependencies, it will run.

Features:

The console is a Lua interpreter with exposure to C functions. The console is also a work in progress. More info here

Type help() to see all the things you can do. Documentation needs work. For more details, see the C code in lua_embedded/  that uses the Lua C API.

Once you start up the program, in the console enter

doscript("path test.lua")

To create a player cube. You can path the cube with mouse clicks. There are some weird glitches and things to clean up, but the terrain should load and unload around you.

Right now it's just pathing in a perlin noise world :P!
