In Thinking with Time Machine, the player controls Chell, the protagonist of the official Portal games.[1] In addition to the series' "portal gun", it also gives the player a tablet-like "time machine", allowing them to record their movements, and summon a double who performs those motions. The player can only use a single recording at a time, with previous recordings being deleted when a new action is taken. Recordings can perform all the actions a normal player can, and the player can also stand on their recording, allowing them to reach higher surfaces.[2]
Most of Portal 2's testing elements are included in the mod, with new mechanics being taught through an instruction board.[2]
Thinking with Time Machine was released for free to existing owners of Portal 2 via Steam on 18 April 2014 by developer Stridemann and publisher SignHead Studio.[3][4] It was one of the top 200 Steam games in the year of its release.[5]
The game was received positively by multiple PC gaming reviewers.[6][2] Alice O'Connor of Rock, Paper, Shotgun positive in a positive 2014 review "for those lacking in some of the social niceties, it’s perhaps the closest we’ll get to playing Portal 2 co-op.” PC Gamer reviewer Christopher Livingston similarly praised the mod, stating that "working with your past self will seem almost as natural as working with a co-op partner".[2] Though writer for Wired Bo Moore praised the overall design of the puzzles, he noted that some lacked "Valve polish".[7] Additionally, both Moore and Livingston criticised the mod for not featuring enough portal-based puzzles, especially in initial levels.[7][2]
