So, when you first switch to Survival Mode, you'll notice that resources are scarce and you need to scavenge for food, wood, and minerals. It's a real challenge, but in a good way! You'll have to craft tools and build shelters to protect yourself from monsters that come out at night.
As you play, you'll be constantly switching between gathering resources, building structures, and fighting off mobs. It's a delicate balance, but it's so satisfying when you get it right! You'll feel like you're really surviving in a blocky wilderness.
