The first thing you do, is go into the crashed ship and take the 2 sunshakes in the back left corner.
Then you run to the starting farmer shack and take all the blocks (just the blocks, not the soil or seeds). You should now have 91 scrap wood and 18 mesh block.
Run to the 1st ruin and build your sled (9x10 slab of scrap wood, with a mesh block in each corner underneath) stand on the sled and hit it with your hammer to move, to go the fastest, aim as high as possible but still hit the sled.
Follow the road up the hill, if you see a warehouse bigger than 2 floors, reset. If you dont see a warehouse, and you are sure its not hidden behind a forest, reset. If you are going for a fast run, reset if you see a lot of water in the way.
Then sled along the flatest terrain towards the warehouse (dont go through a forest) along the way you want to find a village, where you grab a stack or two of scrap wood, and the toilet.
Once you get to the warehouse, find the eleveator and get inside (dont get killed by tapebots). To get inside you place the lift right next to the elevator doors, place a toilet as close to the doors as possible, get in the toilet and go up, then once you are above the doors jump out of the toilet. You should now be ontop of the elevator. Use the normal toilet exploit to get into the elevator.
Here you want to press the button once, and start building your cube (6x6x6 hollow cube of scrap wood). When you have your cube, press the button again and get inside the cube. You are now inside the warehouse.
Now you just navigate through the first floor, get to the second floor, and get through the second floor.
