Porting in process (hopefully)

So, I'm currently working on porting my code to Windows and Linux (not MacOS, since they're openly hostile to games).
As of right now, I'm at the point where everything is broken and nothing event compiles after what's basically a weekend's worth of work.
The Picosystem API itself shouldn't be too hard to replicate in SDL, but getting the build and cross-compilation up and running has been a nightmare.

Hopefully I'll be at a point where I have at least an executable that opens a window, by the end of next week, so I can get back to features.
Next up would be more weapons and giving the player a more varied moveset, but I really want this out of the way first, so more people can try the game.
