Visuals and Walljumping and whatnots

So this update was supposed to happen last Friday, but hooray for health issues.

Anyway, I upgraded the visuals to the game with some baked lighting and a smattering of post-processing effects via Unity's Universal Render Pipeline.

Also of note: I finally fixed the walljumping, which now actually works as intended and doesn't just constantly bug out. 

The perceptive player will notice the presence of a large tower in the center of the map, and a new bit of text on one of the far walls.

Aaaaaand there's now a Pause Menu with a handful of options available (though the only ones that work at the moment are the volume sliders for the music and SFX).
