In reference to a video game, I might say:
"Braid is a rewarding puzzle game with beautiful art."
In this sense, I don't mean art as in a specific piece of art in the game, I don't mean art as a skill or craft, and I certainly am not referring to "the" arts. However, those definitions are all I could find in dictionaries.
So, what can I use to refer to something's own general style or visuals?
