When a game is offensive, it's usually designed to be that way. Nobody thinks the makers of Postal or Grand Theft Auto are out to give people a warm and fuzzy feeling. Other times, games that are meant to explore a sensitive issue are misconstrued as offensive; Super Columbine Massacre RPG is a great example.

But could a game be accidentally offensive?

That seems to be the case with Pixel Marathon, an endless runner from developer Tinker Games.
