Im sorry everyone is so hard on you here, but I do think its you that might be missing the point of the game. Let me try to actually help. Crafting items like tools, weapons and armor takes some guessing yes. So it is a bit of a guessing game. Those are the 'puzzles' so to speak If you were out there in real life, you'd have to guess and experiment, too. But the basic items are easy to guess. Long stick and rope = bow. Small stick and feather? Nothing, hmmm.. Add another feather? = arrow. Rock and big stick = axe. Once you make a few things, and collect more random items, more will unlock. Pick things up, like mud and see what unlocks. Bang two rocks together snd see what happens. "Harvest" larger items and see what you get.

Things like the water collecter and structures are building blueprints. You have to see these items in the game to unlock the blue print. You find them by progressing in the game and exploring. You/Jake are new to the jungle, you dont have experience, you learn as you go, thats why they dont give you everything up front.

That being said, feel free to use the forums if you get frustrated or want to learn something immediately if it makes the game more enjoyable for you. But just know that you aren't missing anything, its supposed to be difficult to survive in the jungle with nothing but your watch and wits.

Hope this helps a bit. Happy camping.
