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

Brilliant concept with very stylish graphics for the chambers. Fun puzzles, easy to learn gimmick, the only thing that's lacking? It's disappointingly short, even as far as mods go. I'm not sure if it was due to time constraints or whatever, but it would have been great to see more chambers in during the main game mode.

Otherwise this is a fantastic mod, and is great for any Portal fan to pick up.

It's a very good mod that takes off from the end of portal 2, so play portal 2 if you can before you play this

The Mod is certainly well made. No bugs or anything as far as I can see it.
The Time Travel mechanic is more like in "talos principle": you leave a copy of yourself that does stuff.
So I would definatly say you should play it. I mean it's free... so who wouldn't?

Problems with the game however:
- too short
- too repetitive
- too few actual "portal"
- too easy

The game is really short (Level wise) and really easy (if you have played any game with time copies). Instead of difficulty the levels offer alot of repetition. One in particular was annoying since you need to do the same reall long task twice even though you already have figured it out after the 1st one already. And lastly the Portal gun isn't acutally used that much. 80% of the levels dont even have portable surfaces.
