Finally started adding some wall art.  Its basic, but it definitely added some much needed depth and art.  I just using simple tilebased, 64x64 pixels via Aseprite.  There is a lot of room for improvements and I have a lot of ideas, but im also focusing on building out the first couple of levels and having an actual wall in the level really allows me to focus on the design and flow of the level.  Im hoping to use these tiles as a basic foundation and build up from here.
