I love the Talos Principle 1 and 2, if you liked Portal you will probably like them, they rely less on platforming and more on puzzles that require you to use the puzzle elements in creative ways. The puzzle elements are easy to understand, like a jammer beam gun which jams a force field door when placed. One of the early and obvious tricks is if you have two jammers, how you can bring them both with you through a door.
They also have quite a bit of humanist philosophy, in my opinion they do a good job of being relentlessly optimistic in a way that feels genuine without being overbearingly techno-optimist.
