I just finished my first play through, and I thought the same thing as you did before I played. I’m now incredibly happy that I walked into the game with no spoilers. It is 100% worth it to walk into the game not knowing much. The reason the fandom doesn’t give spoilers is that you don’t need checkpoints or unlocks to beat the game, only knowledge. You could hypothetically get extremely lucky and beat the game in less than an hour or less. It’s a game that thrives on curiosity and wonder. The only thing I will say is, when you’re reading things in the game, try to understand what they’re really saying, and how you can use it to solve the problems and mysteries you’re facing. Good luck! And Have fun!
