I can explain a little. The colors kind of clash, or just don't really look like they fit together. To make it look more futuristic, the walls could have been a bright white, and the gameplay area could be the same texture, but greyed out. The outlines can either stay or go, that would look good either way.
Even though it ties in to the story a little, I feel like the pixel person clashed with the rest of the game, and he should've been an abstract shape or a drawing.
