Nelson Tethers: Puzzle Agent

The game follows Nelson Tethers, an agent who is part of the FBI's largely ignored "Puzzle Investigation Division." After the latest shipments of White House erasers fail to arrive and mysterious letters with obscure puzzles arrive instead, Tethers finally finds work. Further investigation leads him to the abandoned eraser factory in the wintry forest town of Scoggins, Minnesota. But as soon as he arrives, he discovers that things are not as they seem.
