You’re in a cave but have no idea how you got there.
Use the crack in the wall you’re standing next to on the left. There are some loose STONES. Walk to the right to find a lake. The surface is frozen. Walk across the lake to the other side. Keep walking to the right until you reach a pillar with a strange stone to the right of it. Use the stone to look under it and take the PAIL. Return to the lake on the left and cross the lake again to the left bank.
Use the pail on the lake to get some WATER. Look at the pail and then use the pail [right click] to find a FISH (5/5) and then walk to the right until you find two guards. Throw the stone from your inventory to the big rock to the right of the guards as distraction and they will leave, checking out the noises. Walk up the ramp and walk through the tunnel to the right.
Climb the vertical tube on the left to climb out at the top. Walk to the right and find two small huts. Use the one on the left and take the big LOG from the floor. Leave the hut again and enter the one on the right. Talk to the alien and learn where you are. Find out how he gets his food and he’ll tell you about the space ship next to the hut. Ask about the MICROCHIP on the shelf and you can have it since the alien couldn’t get it to work.
Take the STONE with encryption from the bottom shelf of the cabinet and in your inventory put the chip in the stone. Use the blue pot on the floor to find a red KEYCARD. Leave the hut and walk to the right to see the space ship. Use the keycard on the ship (5/10) but you can’t leave with it.
Walk further to the right and find some cracks on the ground. Use the big log on the cracks to make a hole and then climb through the hole. Use the stone with microchip inside on the opening of the teleporter and you can go home.
