For some reason, the game https://steamproxy.net/steamstore/app/235980/Tetrobot_and_Co/ reminds me a lot of Portal - not story-wise, but in the unique puzzles. And for some sectors, you can solve the puzzle more than one way. :)

You might like the game http://steamproxy.net/steamstore/app/209630/ . It's probably more like Portal 2 than Portal 1 in that there's probably only one way to solve puzzles, but it's probably more like Portal 1 story-wise in that it's shorter. Can't say for sure yet, since I'm not very far (stuck on a puzzle, sigh).

Thanks for the gift. I'll have to fire it up soon. My son appears to have already taken an interest in it so I may have to share with him lol.

i forgot to but thanks for portal

It was my pleasure. I hope you enjoy the game, it was a lot of fun pimping out my rides and cribs :) And there were a lot of Kodak moments too hehe.
