I think if I played this game myself I never would have finished it. I actually watched a play through on YouTube by someone that was actually competent at puzzle games, and had a great experience. Then I ended up playing through it myself a few years later, knowing the story actually helped keep me motivated. It really is an incredible game.
Even if the common advice is to avoid spoilers, I’m glad you found your own way to enjoy it :)
I’m sure I could play it again myself and still enjoy the atmosphere, even if the discoveries weren’t new. Or maybe it would be fun to watch a stream of someone else playing for the first time instead!
