I have no clue how to export to Linux, but I'll take a look after I'm done optimizing memory. I've noticed the game uses up ~530 Mb of VRAM, and a few users have shown me the specs for their laptops allowing only for 128 MB of VRAM. In the next few days I'll have a build that can run within the 128 MB limit, at the sacrifice of a **little** bit of detail.
