General information
This is a complete walkthrough which allows to get most of the missable achievements in one playthrough. Please note that this game requires at least three complete playthroughs in order to get all achievements.

This guide skips all map and light items as they’re not needed and picking them up prevents from getting two achievements.

There are five collector’s items hidden in the game on each difficulty level plus two additional ones received for finding the first five and for completing the game. They’re in the same locations on each difficulty level.

Hidden object scenes are going to be referred to as HOS.

Certain puzzles are randomized so no step-by-step solution could be included.

How do I know what maps look like, in order to avoid them to get the no pickup map achievement?

A well done guide and a helpful walkthrough. Thx for this. Sure this game is casual, but the extreme difficulty level is harsh (because of the limited time). It was very useful to check your guide to be fast and don't waste time.
