"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.”

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!

If you liked Portal or Portal 2, and aren't aversed to mods, then you should try this game. Ultimately, the only gripe I have is that it was so short.

A good game, short but with a very interesting concept.

This game isn't without its share of bugs, there are a few crashes and glitches to endure - however it's a short and fun addition to the original concept.
Yet only real criticism would be the lack of explanation of what to do when interacting with panels at the start and end of the game. Other than that, well thought out and kept me occupied for a good few hours!
Definitely give this a shot.

So this essentially takes the record mechanic from the blinx games and attempts to build an entire game around it, and it fails to do so.

For this game its easier to lay out my problems with bullet points than a paragraph.

1: the mechanic of using your copy to give you a boost onto higher platforms is a waste of everybodies time, its a lazy way to extend the game by making you go through the recording just to jump higher.

2: the actual usage of the time machine device is never tutorialised properly, i was standing around for about 15 minuites just figuring out how exactly it works, again another massive waste of time that couldve been avoided by a proper tutorial (or better yet a more streamlined system)

3: as stated above, i believe the usage of the time machine is too complex, going through many different actions, while say pressing a button, recording for 20 seconds, then automatically reversing time back to the original point and playing the recording, is FAR simpler and achieves the exact same end goal.

4: the art design is just plain dull, its bright white bloom heavy lights, and more bright white bloom heavy lights, and nothing else.

5: due to the fetish of having many cubes and laser fields to vaporise them, you can end up 5-7 minuites into a puzzle, accidentally twitch your thumb, and suddenly your cube is vaporised, meaning you have to go through all that crap again just to get back to where you were, this couldve been avoided by better level design

I literally cannot find a single redeeming factor for this game outside of the main, poorly implemented mechanic, only play if you are extremely desperate for the gimmick, otherwise avoid like the plague.

overall, when i heard about this game, i expected an ok puzzle experience, not something amazing but ok, what i got was a situation where someone threw crap at a wall to see what sticks, but also included the crap that didnt stick for some reason.

This was not a very fun game, and the only mechanic I liked was the time-traveling.

I thought this would have had time travel, like... time bombs in Black Ops II's Buried. Not recording puzzles like in Ratchet and Clank: A Crack in Time.

4/10. For effort.

Have you ever thought of enjoying life outside? well remember the ending of portal 2 dont worry i wont go spoiler alert but thought of having the game way more harder well Thinking with Time Machine leads you to the past you have a small computer and there you can do a action and record it then you press play and your self is there she helps you (you in game) to finnish puzzles and levels dont worry the game isnt long well thats the sad part its a 30 minute game 1 to 9 levels i believe. Are you excited for portal 3? WELL PLAY ALL THE PORTAL GAMES BEFORE PORTAL 3 COMES OUT download the mod and enjoy remember the mod is free.
