The past within is a very unique game in terms of gameplay and drawing style, as it is a game that allows two players to invite your friends together, one to go back in time and one to go to the future, and work together to solve all the puzzles, I believe it will be a new two-player experience!

First you need to invite a friend to join you, and both players need to communicate with each other by voice chat at any time during the game. You need to make sure one player chooses A and one player chooses B.
