So SeeThrough Studios made Flatland: Fallen Angle in 2012, a game based on a 19th century novella. Keeping in line with the studio's interest in delivering narrative in genres that don't necessarily push the boundaries of story telling, it plays out in a rather interesting way. If you are interested in Particulars (or you just want to play a really sweet game!), go download it for free!
Based on a 19th century novella, Flatland: Fallen Angle is a noir tale of revenge, political uprising, and breaking your enemies into tiny pieces! Set in a world of only two dimensions, the player takes on the role of a once-powerful polygon – now reduced to a lowly triangle – who will do whatever it takes to reclaim his stolen sides.
Would be great to hear what you think of the game too. Personally the narrative absolutely hooked me, and I'm glad the guys kept the story telling up in Particulars!
