The Microsoft Store / PC Game Pass version of OMORI is not supported.
It uses a different engine that doesn't let us add plugins.
By default, Windows Explorer hides the extensions of file types it recognizes (.EXE, .PNG, etc.). It's important that these be visible when setting up mods or asking for support, so we will make sure Windows always shows file extensions for all file types.
Open a File Explorer window (it doesn't matter where).
Click the View button at the top of the window.
Click Show > File name extensions.
If you've already downloaded OMO CEP, skip this step.
Scroll to Available releases at the bottom of the page and click the download arrow next to either OMO CEP for Windows or OMO CEP Lite for Steam Deck.
