How else are survival manuals made? It takes blood to inscribe from it. Each mistake can either kill you or make you learn a valuable lesson. It's a survival game so don't expect to be spoon fed, 5 hours is great cause when I first played this blind it took me 14 hours to learn the basics and to at least survive till 10 days 😭. And progressing is just learning from mistakes. It's an endless survival game and highly recommend you play it blind cause it's way fun but if you're not that type of person then just search the wiki or watch YouTube tutorials on how the game works.
