Firstly go to Preferences on the main menu, and turn Gaslight off. After doing so click Start. This should unlock the "Cheat" achievement. Now go back to the main menu through the pause screen, and set Gaslight back to On.

Next we will go for "Paralysed", "...", "Eden", "Another Way?", "A New Tale", and "Fearless". While doing this section stop at the stair scene, and use mouse scrollwheel up. This is where Hidden Object 4 is located as a reference image.

Select Start on the main menu, and skip the text until the first choice. At the first choice save your game, and select the 'Try and escape: Run into the blackness' choice. Now load your save, and pick the opposite choice. Continue skipping until you arrive at the next set of choices. Here save your game again in the pause menu.
Now follow this series of choices: Right, Left, Right, Left, Forward, Left, Right.
This will unlock "Eden". Finish the route then load back up the second save.

Now follow this series of choices: Left, Right, Left, -, Left, Right, Left.
Finish the route, and you should get the rest of the achievements.

Finally you should just need the hidden object related achievements. "Secrets", "Fragments", and "Complete Picture". For this you are going to have to play through the game again this time making sure to take it slow to collect the hidden objects throughout the scenes. There is a total of 10 to collect, and I have provided screenshots, with a short description on some for guidance. Some may have the gaslight cursor in the way.

Hidden Object 1:


Hidden Object 2:

(under cursor)

Hidden Object 3:


Hidden Object 4:

I recommend saving before this staircase portion, as it can be difficult trying to get the hidden item due to the scene panning upwards making it missable if you don't click it fast enough.

Hidden Object 5:


Hidden Object 6:

This is during the hallway scene the cupboards will open only for a line of text. I recommend saving for this one aswell as it's very precise, and if you misclick it will move onto the next scene.

Hidden Object 7:

Like the last one be careful there's not many lines of text for this scene as well.

Hidden Object 8:


Hidden Object 9:


Hidden Object 10:
