October Update — Blooming Winter Steam update #6641350

- Updated door sprite to actually be my art and not a stock asset from the Unity asset store :) I am planning on also doing this for all other textures taken from there, which includes the stone walls and floors, as well as grass tiles (though I edited those ones so they aren't as placeholder-y so they're lower priority :)) ... ... I was a lot busier than I expected this month, okay? :(
