Set up a background and an auto-tiling tileset. 

I'm getting really excited about my progress so far. Just sitting myself down for five minutes a day and doing a little bit feels really rewarding without feeling too overwhelming.

EDIT:

Decided to sit down again before bed today and work some more on learning Godot. Ended up adding a cliff tileset with collisions, an attack animation, and a state machine. I love the idea of a state machine and am super keen to learn more about it!
