Windypool.0 is the result of ID's ingenuity. While not listed on the official list of Xhilatren games, it is still considered a part of the series.
Players cannot access any features added in the second game without first completing the first game and progressing to the second. However, they cannot be harmed by any entity, item, or function in the second game. Players from both games may interact and trade items common to both games. This is easily accomplished, as both games are set in exactly the same place.
Windypool.0 is the first game in which two games in a series were combined to form a larger whole that interacts with itself.
