Back to the drawing board. Literally.

Welp. I was all set to go and make the tilemap for the first level when godot decided the tileset I'd made was a compressedimage2d no matter what I did. I've spent part of the night and all of the morning trying to fix it when I realized something else, all the collidable objects are also in a png together; which the work around would be use each of them as an animated sprite in the engine. However, they simply won't work either. I've tried numerous ways to fix this and it looks like scrapping what I got done yesterday and starting over in the code-work/engine as well as remaking the tiles individually today is what I'll end up having to do. 

However, I am hoping it's as easy as just re-starting the project from scratch and doing the tileset stuff first.
