UPDATE 2:
Today, I have mainly just focused on the art and tiles, and though they are still no masterpieces, it was the best I could do. The spritework still needs to be redone, and I have to come up with something for the player, but that can still wait a little.
I also added these direction changing "vector plates", and just put them all over the place. If I have enemies (which should hopefully be done by the next update), I will have the main game loop down, but I still need to tinker with the camera and rooms a bit first...
