I've been playing this puzzle game called "The Witness" like all day. For several hours, at least. I'm writing this post on my phone because it's getting close to midnight and I don't really want to shut it off.
it mainly involves finding paths through mazes, and tbh I don't want to say much else because I feel like it's pretty spoilable, in the sense that the game teaches you how to play it really well and I wouldn't want to undermine that experience.
I heard about it on the Adam Ruins Everything podcast, where I'm partway through an episode about it that gets increasingly spoilery -- I hit a point where I decided it was time to shut it off and get back to it after playing the game. If you're curious, I recommend doing the same.
