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

This is nice... A bit confusing at first, just getting the controls down. The idea is brilliant, very fun, and really trippy. Glad none of this is cannon, that's for sure. The visuals are pretty nice, glowy texturing, mixed with regualr aperture. The only thing that annoyed me though was the open aperture through the windows. Since it was a skybox it made lights look massive..

This mod requires ownership of Portal 2. This review also assumes you already own and have completed Portal 2, my review of which can be read here.

Mod: Thinking with Time Machine
For the game: Portal 2
Developer: Ruslan "Stridemann" Rybka
Publisher: SignHead Studio
Released: 18 April, 2014
Genre: First-Person Puzzler
Setting: 21 January, 2021, Aperture Science Enrichment Center, Upper Michigan, U.S.A., Earth (though in Portal canon, the time-setting would be "at least 50,000 years" after Portal 1)
Canon status: Non-canon
Spoiler-free plot summary: After the events of Portal 2, you, Chell, discover that the field of wheat you enter upon exiting Aperture Science is actually just another part of the still mysterious science facility. Upon entering an elevator she finds outside of the fake wheat room, Chell is given back her Aperture Science Handheld Portal Device, this time with a pseudo-time machine PDA attachment.

Full review: Thinking with Time Machine (named after Portal's advertising campaign "Thinking with portals"), is a mod relatively the same length as Portal 1 (my review of which can be read here), and is equal in difficulty. There is absolutely no story, apart from one scene about half-way through the campaign.

The main game mechanic of Thinking with Time Machine is pretty self explanatory; using a device which records your actions, which you then replay, in order to solve test chambers with your past self (other games similar to this are Time Slip for the Net Yaroze and Chronotron on Kongregate).

The ten test chambers in the campaign are absolutely brilliant; not too hard, not too easy, and leaves one in awe at the genius behind them. Though I did have a bit of trouble with chamber 5 because I wasn't informed about a new game mechanic, cubes and spheres being able to float on the ceiling, so I wasn't aware it existed. Not being able to solve this chamber, I gave up and decided to look up a video guide to solve it. What's even more infuriating is that this mechanic is only present in this one chamber.

Unlike Portals 1 and 2, there are no advanced or challenge maps or modes included in Thinking with Time Machine, which is a bit disappointing, as I would have liked to have played in some more difficult chambers, and have a longer experience. Fortunately, carried over from Portal 2 is Steam Workshop support. Though there is no official co-op campaign like Portal 2, co-op maps can be made with the map maker.

As said before, there is very little plot. All that's established is that it's the year 2021 (which, in Portal canon, is an outright fabrication), and ATLAS and P-body from Portal 2's co-op campaign are using you to find a time machine GLaDOS has hidden somewhere.

A short, simple review for a short, simple mod. Do I recommend Thinking with Time Machine? Yes; it's free, it can entertain you for the day, and it's a nice piece of dessert after the meal that is Portal 2.

This mod is... Mediocre. The new mechanics are pretty fun. However, the story is vague, and the game tends to crash a lot.

Update: Most bugs now appear to be fixed, and if you have any, make sure that first of all you aren't in the beta for Portal 2, since if you are it will CTD as soon as you get past the Valve intro video, if you have sound issues, rebuild the sound cache or do a clean uninstall and reinstall it for the fixed cache direct, make sure you have Portal 2 installed on the same HDD, and if all else fails, verify the integrity of the game cache on both TWTM and Portal 2.

Anyhow, onto the review of the actual game/mod now that I've had time to play it after fixing the bugs;
First of all, if this was a workshop submitted mod (not possible due to the extent of the gameplay and asset changes in some areas, therefore the store mod) it would most definitely be one of the highest rated community campaigns along with 12 Angry Tests and Designed for Danger. It may not be the strongest in terms of pure level design and perfection of the core Portal formula, but it certainly makes up for it through having the most significant gameplay changes to come out of the Portal community yet. If you're a fan of the Portal series, this is definitely a must play, especially considering it's free, you'd struggle to not got any sort of enjoyment out of TWTM, even if you didn't complete it or care for the TM mechanic much.

It doesn't have the strength of a proper retail game which is as to be expected due to the fact it's a community created mod by a couple of guys in their spare time. Most of the downsides amount to length of the mod and levels of polish. If this had been picked up by Valve for instance and given another few months of development time to polish it up and add to it, it could have no doubt been sold as a single player expansion to Portal 2 and have been worth paying money for.

In summary, if you're a fan of the Portal games, play it. It's free, you've got nothing to lose, and there's a very strong possibility you'll like it. Interested in seeing what the developers of the mod go on to do, since this shows a lot of promise from them in getting a job in the industry or creating their own games.

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

I seriously have never played any portal 2 mod quite like this. It is incredibly awesome, even in the first few puzzles I have played. I love the new graphics style they have given this mod, with the glassy and polished techy rooms... It's so amazing. It does take a while to get used to the time machine controls.

Alright, if you ask yourself "Do I need to download this mod"(Which is weird because it's free and almost everyone say it's awesome), this review is gonna show you exactly why you should.

Plot
Ok, so the plot is kind of a meh, and a bit cliche as a time travel story, but the start is amazing as you have already seen in the trailer.

Length
It's not as long as Portal 2, but as it works on the same principle of Co-Op(Think for two players), so the difficulty would make it feel longer.

Difficulty
This mod is much more challanging than the actual game. Really, even Portal 1 isn't hard like some of these chambers. Lovers of challanges, you're gonna LOVE this mod.

Differences From the Base Game
Ok, almost everything is now completley retextured and looks awesome.

Overall
Overall, this is a great mod, very challanging, a bit short, and while Portals are not the main mechanic anymore, you should all play this. It's also free and you can see your legs.

Pros:
• It's free!
• It runs fantastically with no bugs as far as I'm aware. It looks like it was made by Valve themselves, or as if it was its own game!
• Brand new mechanics. It's not about the Portal Gun, it's about the Time Machine and the Portal Gun.
• You can see your legs!
Cons:
• It's free! The developers of this mod deserves money for their valuable work.
