"The recording mechanic is fun and highly inventive despite some issues, and we feel the possibilities were suitably explored within an hour of playtime."

“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 overal when you look past ones scientific, philisophical, 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 sycopath ai (wheatly), and a murderous and mentaly unstable ai (Glados), LOL.

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 like Portal, you will enjoy this one. You just need to think outside the box.

Very frustrating. Not difficult for the logic solution but only for the required ninja skills.

This game is boring... it is essentially a single player version of co-op Portal. but since you have no friend to help you, you play as player 1 while recording, and then as player 2 as the ghost of player 1 replays.

The gimmick is kinda cool but it got really boring. I expeirenced many bugs and a lot of crashes. Also very poor story line.

Remember this is my opinion you don't have to like it. [i/]

Great concept, even more mind bending than Portal 2, generally enjoyable.

Crashed multiple times on me, which I could bear I suppose. Managed to get it loading but was halted on the first level because it doesn't explain anything of what you are suppose to do at all. I'll have to return to this one later when it's all fixed.

Though a short game I am fassicated in this new mechanic. You really have to think outside the box and completely change the portal thinking. It is all timed based too, so make sure you count the seconds in your head as if you were going to do this in the future and the past. Highly recomended to play for 2 hours. 9/10
