Work on Assets started

Decided that I'll work some more on the game after LD46 weekend. Started with making assets more 'proper'. On the first iteration were high shelves and 'wet floor sign' (which now should actually look like one...)
After last iteration I decided to also change main floor colour, because I noticed some issues because of overlapping colours between shelves and ground. All three iterations (with the origina LD46 version at the top and final result at the bottom) are visible on screen below!
