About the game
You and a friend play two detectives, Old Dog and Ally, who are pulled back into a case against a killer they believed was locked away. It is a point-and-click puzzle game with a hand-drawn comic look. Each of you works from your own location, and your screen is not your partner's.
You play on separate devices, and the two can be different. PC, Mac, iPhone, iPad and Android all play together. One of you creates the game and the other joins with a short code. The game has no voice chat, so you keep a call open on the side to describe symbols, numbers and objects. Some puzzles ask you to draw on the screen.
The case takes about 30 to 60 minutes and costs nothing. It ends on a cliffhanger that the next game in the series picks up. It is easy enough for new players and suits a pair who like talking things through.
