The per-pixel movement we have could be costly once scenes get bigger if we continue natively checking over every time for a potential collision, so that's being curbed early and easily with spacial hashing.
Also added loading of tiles from a while - possibly going to try procedural chunk gen.
Been thinking about how much friction I have with putting art in little experimental things and ways that could change. Experimenting with sketching out in ink and colouring in Gimp.
It ended up being surprisingly quick, and the bad quality source picture with no regard for lighting turned out to be easy to work with!
