It is intended for 'veteran players', being more challenging than the official games. The developer has stated that the mod is intended as a smaller-scale complement to the original game, in contrast to other modifications such as Portal Stories: Mel. Unlike Portal 2, which it is based on, the game's initial release did not feature a co-op mode. Therefore, careful usage of puzzle elements allows the player to have a duplicate of any puzzle element that can be brought through the time portal. A future variant of an object brought into the past does not create another future variant of itself. While past objects cannot be taken through the time portal into the future (causing a paradox), future variants of an object can be brought into the past. However, objects in the future can be moved independently of their past equivalents. If an object – such as a cube or a conventional portal – is manipulated in the past, it moves in the future chamber as well, causing its previous copy to fizzle. The game also involves solving puzzles with other testing elements introduced in the official games, such as buttons, cubes, lasers, and light bridges.

Unique to the mod is a third 'time portal', allowing the player to traverse between the same point in two alternate versions of the test chamber, located respectively in the past and the future. Players are equipped with a 'portal gun', allowing them to create holes that connect disparate areas in three-dimensional space.
