God of Light: Remastered

Story-related; cannot be missed.

There are a total of 6 trees to revive:

1. Celestial Tree (Chapter 1, 25 levels)
2. Stone Tree (Chapter 2, 25 levels)
3. Azure Tree (Chapter 3, 25 levels)
4. Snow Tree (Chapter 4, 25 levels)
5. Space Tree (Chapter 5, 25 levels)
6. Desert Tree (Chapter 6, 25 levels)

Each tree consists of 25 levels, and in order to unlock this achievement (and all of the individual achievements for reviving each tree), you simply need to complete all 25 levels in each chapter by lighting up the endpoint with your light beam. Stars, points, and fireflies do not affect these achievements, although you should be aiming to solve all levels while collecting all three stars anyway.

Since there are a total of 150 levels, and that would be a lot of videos or screenshots of the solutions, I've provided a link to a playlist of videos for all level solutions. It is highly unlikely that you'll need these videos though, since the majority of levels are very "linear" in how to solve them. By that I mean you'll move the starting beam and find a mirror, and that'll lead to you to the next one, and so on. There were only maybe 5 or so "tough" levels where I spent some time trying to figure out how to get all three stars. It was in these instances I'd make use of the firefly to help me along.
