Demo 1.07 - More optimization, buff & stuff - Also Linux support!

Huge thanks to tsjost on Twitch for helping me figure out why the Linux build wasn't working! (Something to do with OpenGL Core, had to use Vulkan. Will investigate more when I have a Linux box of my own)

Those 3-tile high jumps are pretty dang-gosh-heckin' tight, so I made them less so. You now jump about 5% higher, making those jumps much less annoying.

Also some people found a shortcut instead of the main route by accident, so I made the proper direction a bit more obvious.

And stuff is probably a bit more optimal, once again!
