“Technically the ‘main feature’ in the Thinking with Time Machine mod is a time machine ..., which is great and all but look, LEGS.”

If Valve made games with the number (CENSORED), then this would be the (CENSORED) game in the series.

Very unique (directed towards time machine aspect). The textures are great and very futuristic, yet, does not cause lag on slower Computers. I run this on my Asus transformer book (windows tablet) and I have it on medium graphics and I have no lag whatsoever. One thing that makes zero sense is how the levels are upward. You have already gone extremely far up, and, as seen in portal 1 the ground is not that far above glados's lair. It would have made more logical sense to go down instead of up. But what the heck, its a great game overall when you look past ones scientific, philosophical, and OSD, along with the fact of realizing portal already lacks legitness to it, with a portal gun and time machine, as well as a psychopath ai (wheatly), and a murderous and mentally unstable ai (Glados), LOL.

Thinking with Time Machine is amazing, using a time machine to solve puzzles. This new feature is just great to play, was fun to think what I should do at the same time but sadly these puzzles were not hard enough to keep me more than 30minutes in a room. It took time to do everything but the puzzles themself, were just easy. Simple story, go back in time to safe Glados from the two bots who you could play in Portal 2 Co-op.

The tutorial itself was really helpful, if I would had seen it first. I would rather mark the small video with something big so users can't miss the small video, like me. Sometimes the game crashed but this was not annoying much, just validated the game file and worked again. Well, it still looks like Portal 2 but the gameplay feels like a new game of Portal where you can only open on few spots a portal. Thinking with Time Machine was really fun, just was a bit short.

All in all a game for people who likes to puzzle and who owns Portal 2 of course.

Puzzle - 4/10 (difficult of them all)
Gameplay - 7/10
Length - 2/10
Design - 8/10
Fun - 9/10 (there were some places which took me long to do)

Short but it makes it up with being creative and brilliant. The whole game is like a one man coop adventure. The test chambers weren't too complex yet challenging sometimes. If you can get the hang of the time manipulation, you'll be thinking with 88 miles per hour.
(PS. You can see your legs if you look down, hell yeah!)

Thinking with Time Machine, or T.W.T.M. is a brilliant Portal 2 modification. The mod tries to continue the events after Portal 2 but of course it is unofficial and so this is not the continuation and this is not the third Portal game. However, if you're desperate for a Portal 3 right away, this is your best bet right now. The modification adds new gameplay, and of course one new crutial feature, time travelling. The mod still has Steam workshop and you can create your own testchambers, just like Portal 2 which I found exciting and great! There's a slight change to the graphics which is also good. Overall, I like the modification and think it's great! I reccomend it to anyone but you must play Portal and Portal 2 before you play Thinking with Time Machine as it kind of spoils some of the storyline! Reccomended! Thanks for reading!

Thinking with Time Machine is not only a fantastic spin on the ending of Portal 2, it's a great game in it's own right. The new mechanic takes a bit of getting used to but once you do it's fun and challenging. The custom areas and animations are divine (Save for a few graphical bugs.) and y'know what the best part is? It's FREE. TO. PLAY! What else is there to say? Download now! :D

Thinking with Time Machine is a Portal 2 mod that includes 4 tutorial chambers and 9 test chambers (actually there're 8 test chambers because you don't really have to do anything on the last one).

It introduces a very interesting device, the Time Machine, which allows you to record and replay your movements, meaning that there may be two of you at the same time. That brings new possibilities and you actually have to change your way to think when trying to solve the puzzles.

The game is kinda buggy sometimes but overall I found it really fun to play and certainly challenging - some test chambers aren't exactly straightforward. In addition, this mod is available for free (it only requires you to own Portal 2) so I highly recommend to give it a try.

If you don't have any friends, you can co-op with yourselve. You can also see your feet. NOW THAT'S COOL.

"Thinking with Time Machine" (TWTM) is a fun, creative, and challenging mod for Portal 2. In it, you are given a, you guessed it, time machine, which allows you to replay 1 recorded copy of yourself performing an action or series of actions. To solve the continually-difficult chambers, you will have to think far ahead, navigating new flourescent-themed areas. Even though it is a bit short if you have lot of Portal experience under your belt, TWTM continued to amaze me with stunning graphics, unique puzzles, and an overall dazzling experience. And considering it's free with a purchase of Portal 2, give me a good reason for you to not download this title now!

This is a very short mod for portal 2 which is meant to take place directly after portal 2 ends. The focus of the gameplay isn't so much about manipulating time as it about puppeteering your clone to get you through the level. It is like the coop levels, but you play both roles. The level design is good in some areas and poor in others; the chambers are very creative and utilize the new gameplay concepts very well, but can be very confusing at times for various reasons. The story is minimal and although the conflict and resolution are introduced, they are not really extensively developed. The times at which the story is conveyed are scarce and consist primarily of small bursts at the beginning, middle, and end.

Over all, I would reccomend this game as sort of a novelty.
