Telltale's Nelson Tethers: Puzzle Agent has now arrived at iPad and iPhone. The iPhone version will cost you $4.99, and the iPad version $6.99. The PC/Mac version will set you back $9.95. A WiiWare version is in the works.
For those who don't know, Nelson Tethers is the debut episode of Telltale's new "Pilot Program", which, as its name suggests, aims to make one-shot episodes that test whether or not people are interested in a certain game. If people are interested, a full series is developed and vice versa. It was developed in collaboration with Grickle-creator Graham Annable, as can be seen in the game's art style and felt in the game's tone.
