Ori and the Blind Forest: Definitive Edition - Nintendo Switch

This is not intended to be a full guide for the achievement, but a fix for a known bug that I got hit with and found the solution for online. This bug seems to affect all systems (ie PC, Switch too).

If, after you have been to every area and collected every item, you are stuck at 99% in Moon Grotto, you may have been affected by this bug. There is an area at the bottom of Moon Grotto that is covered by lasers (below where my Ori is on the map pic included below). You are required to go through this area in order to progress the story, so it should be cleared, BUT, if you died after completing this area, but before saving, it seems to trigger a bug where the lasers are on, but the area is not considered cleared. There is no second block that spawns on your return visit to this area to block the lower laser. IF this happens to you, you can use the following cheat code to jump over to the handle that turns off the lasers:

cheat code: up, right, down, left, right stick press, up, up, jump

To do this, just hang on the wall above the bottom laser, and enter the code quickly with your controller. You will teleport over and above the switch, allowing you to traverse the area below a second time and get credit for the full map clear.

I can personally confirm that it works on the Xbox One and it saved me several hours of another replay. The second screenshot is of me on the "correct" side of the laser after entering the code. I hope this helps you too! If you're leaving negative feedback, please comment as to why, so I can improve this solution.
