For this walkthrough, I will simply explain how to get all four of the endings, starting with the Main Endings of each of the four levels, then the Alternative Endings for each as well as the different Symbols you can draw to look around and/or manipulate the environment.

----------

The Next Hurdle: Save the Teddybear
   Rotate left twice to find a photo which teaches you the Zoom Out Symbol, which is a line going downwards. Use it to zoom out, then rotate around to the other weights, where you will see some kind of 6 neon symbol on them. This is the Lift Symbol, which allows you to lift weights. Return to the sphere, and use the Lift Symbol on it to get the Main Ending.

Following Role Models: Catch the Ghost
   Move to the side of the building where the ghost is leaving from and look at the photos. These photos have the Capture Symbol, which allows you to capture ghosts which are standing still. Now, follow the ghost until you see a point where he is standing still, and then use the Capture Symbol to get the Main Ending. If you go one step too far, you return back to the start.

What They Expect: Follow the Arrows
   Move forward, then turn left until you see a drain with a neon symbol over it. This is the Drain Symbol, which allows you to drain things away through drains. Now, head down the main road until you hit a wall with a drain. Use the Drain Symbol on the wall, then keep on following the road until you end up back where you started to get the Main Ending.

The Road Less Travelled: Find a Path through the Thicket
   Move forward, then turn left until you see some neon symbols.  Follow them, but pay close attention to them when you get close, as these are Cut Symbols which can cut away shrubs. Follow the path of symbols until you get to a clearance, then turn left until you see more neon symbols. Follow them until you hit a dead end of shrubs, then use the Cut Symbol to clear a path. Do it five times to get the Main Ending, and if you have followed this walkthrough, the Ending of the game.

----------

For these, you will see which Symbol you need to use in order to unlock the Alternative Ending, and where you need to use it.

The Next Hurdle Revisited:

• A Coffee with the Nighthawks (Capture) - There's a ghost in the café to the left of the weights. Use the Capture Symbol on them to unlock this Ending.
• Swallow the Skyscraper (Drain) - From the side of the weight pinning down the teddy bear where you can see the photo for Zoom Out, look up until you can see a storm cloud with a drain hidden in the eye of it. Use the Drain Symbol on it to unlock this Ending.
• Find the Fruits (Cut) - From where the bunch of weights are, look up into the tree and use the Cut Symbol to unlock this Ending.

Following Role Models Revisited:

• Open the Crate (Drain) - To the left of the first building you see, there's a box with a drain on top of it. Use the Drain Symbol on it to unlock this Ending.
• What the Crane Lifts (Lift) - Follow the ghost until just before you would go under the crane. Instead of following, turn left until you see a weight, then head up to it and use the Lift Symbol on it to unlock this Ending.
• Look behind the Shrub (Cut) - Turn left a few more times from where you saw the weight to see a shrub. Use the Cut Symbol on it to unlock this Ending.

What They Expect Revisited:

• The Sign Maker (Capture) - For this, you need to head to the right hand road, then turn right and up until you see a ghost on a sign. Use the Capture Symbol on them to unlock this Ending.
• Pick up the Windfall (Lift) - For this one, you need to follow the right hand road, then turn left and head towards the bridge. But before you head down, look down and you should see a small weight. Zoom in on it and use the Lift Symbol on it to unlock this Ending.
• In the Trees (Cut) - Head to the end of the right hand road, then turn left until you see a strange tree. Use the Cut Symbol on it to unlock this Ending.

The Road Less Travelled Revisited:

• Make your Troubles go away (Drain) - Head to the billboards on the left of the tunnel, and zoom in on the one with the 'Make your Troubles go away' slogan. Use the Drain Symbol on it to unlock this ending.
• The Top of the Pole (Lift) - Follow the neon symbols to the clearance, then turn left and then look up until you are able to zoom in on a weight. Use the Lift Symbol on it to unlock this ending.
• Follow the Road More Travelled (Capture) - Enter the tunnel and look right to see a ghost. Use the Capture Symbol on them to unlock this ending.
