I've seen videos. Seems similar to Rust. I've found myself playing Minecraft though as a more relaxing-type game, more like Portal, less about survival and more about exploring/building.

I finally played Journey but haven't put hardly any time into it. I did enjoy a game called Superliminal from a few years ago. Puzzle-ish game like Portal involving perspective. Pick up objects and they change size depending on your perspective. Need to research more indie games like that, smaller clever things.

I need to try Before Your Eyes, which is more like a story than a game. But the screen changes whenever you blink.
