“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.

Do you like Portal, but solve every challenge without any effort? Do you like Time Travel Puzzles? If you answered Yes to any of these questions, This is the Mod for you.

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 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

Some genuius decided Portal wasn't complicated enough, so instead of headache, you get a migrane. 5/5 Stars. Better than Hospital Tycoon

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!

Much like playing the multiplayer co-op by yourself. Very challenging and fun, you will have a hard time putting it down. I looks like they had the backing of Valve with this from the looks of the opening video.

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!)

Think of this as Portal 2, with less portals. And more jumping. And time machines. Also, legs. Don't forget the time machines. By the way, did I mention you had legs? Oh of course, i remember now! YOU HAVE LEEEEEGGGGGSSSSSS!!!!!!!

11/10 Would look down at legs again

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.

It was great fun, and it is a very solid mod, only two bugs that I have noticed;
1) if you crouch and jump the the player model disapears or is mostly transparent(not a big deal)
2) everytime I catch a block in the air, and then have the the past me do the same, she doesn't catch it and thus, doesn't have the block, ruining my stategy. Good game.

This is hard to write a review for. Take what I say with a grain of salt.

PROS
  • The concept of a time machine is a good one, and the mod carries it out very well.
  • The chambers look very nice, and they bring a new feel to Aperture.
  • The story behind the mod is a nice one.

CONS
  • Some puzzles are incredibly difficult to carry out, since they require near-perfect timing, specifically Chamber 6 and Chamber 8. This makes them tedious to solve.
  • It's pretty short. I only had about an hour and a half of playtime. I understand it isn't a whole new game, but it is only about one-third the length of the first Portal game. (10-ish chambers)
  • There's no voice acting, except for a few lines at the end. I was kind of hoping there would be a companion of some sort to help guide you through the chambers.


Otherwise, it was a good mod. I would also like to congratulate the developers on Mod of the Week.

TL;DR: A decent mod, albeit short and tedious. I would recommend it.
