Yes. It's finally out. No Time To Explain, the source of one of the greatest LunchTimeWasters ever has finally been made into a full game.
It hasn't been added to Steam or any other major digital distributors just yet, but you can buy the game from the official website for $10US.
In addition, there is a season 2 release of the game, with new content, which will be free to anyone who buys the game.
