Super Mario Bros. 3 Remake - Mockup

A mockup for another hypothetical Super Mario fangame, this time of Super Mario Bros. 3.
Featured are tiles and a background designed to more closely fit the theatre-like theme of the original, with painted-on decorations and sturdy wooden flooring. On the right edge is a 'virus' slowly creeping across the worlds - this aspect being based on a dream I had the previous night.
