What are some good puzzle games /r9k/? I'm a NEET looking to keep himself busy, indefinitely, really. I want hard stuff that'll really make me think. I've been playing TIS-100 a lot but I'm working rather steadily on completing it. I want something capable of breaking me.
Layton's your game if you're in a puzzling mood.

Talos Principle. A very original game.
