Truly a masterpiece of a horror game, and a free one at that. Ib has so much of a mysterious nature behind it, that you're continually left with the longing to explore the distorted and horrifying world the developer places you in. The most famed dynamic of this game isn't even the puzzles, which are well-designed and unique to each area. Most people love this game for its character dynamic, specifically between the three main (and pretty much only) characters. Despite being a silent protagonist, Ib is able to masterfully convey her feelings to her cohorts via her actions. Gary and Mary, the other two playable characters, also have diverse traits that wonderfully paint them as opposites and rivals to each other.
