Nelson Tethers: Puzzle Agent

The game follows Nelson Tethers, an agent that is part of the FBI's largely ignored "Puzzle Investigation Division." After the White House's latest shipments of erasers stop arriving and are instead being replaced by mysterious letters with obscure puzzles, Tethers finally finds work. Further investigation leads him to the shutdown eraser factory in the wintry forest town of Scoggins, Minnesota. However, upon arrival, he begins to realize that things aren't quite as they seem.
