basically, if you hear a sound on the left turn right and if it's on the right turn left or else you'll be brought to the camp and lose all your branches. as you walk around, you'll find branches that you can collect to upgrade your campfire, but if your coldness meter is too high you won't be able to collect them. you'll also find a chair that gives you 3 more branches and a lighter that will lower your coldness. you can go back to the camp to cool yourself down and upgrade your campfire if you have 5 branches. you beat the game by upgrading it 4 times.
