As with other WadjetEye games, Shardlight takes a retro approach to its visual style. The pixelated world and characters will strike nostalgic chords with any gamers who remember the mid to early 90's. Personally, throughout the game, I couldn't help but think about LucasArts' 1995 game, The Dig. Where many other classic LucasArts adventure games have the same level of graphics, The Dig conveyed the same realistic (or at least as realistic as this style can produce) look and feel as Shardlight.
Even with Shardlight's low visual graphics, its post-apocalyptic cityscape translates well and is conveyed easily to the viewer. While the characters are very low-res, they are distinct looking enough so that you know who your character is talking to.
Shardlight really hits the nail on the head when it comes to audio. Not only is there an appropriately feeling background score throughout the game, but all of the dialogue felt right and at no point did it seem like any of the voice actors were stiff or bored.
