The worldbuilding and writing of the characters felt really strong! I got a clear sense of the world and the threat. The beginning did feel like it was a little heavy on exposition, but since it turns out it was the character's thoughts, it was a strong set up for the rest of the story.
I agree with both June and Kaz in that the Resist part felt like it was setting me up for something big to happen. The negative agency of that choice felt like it showed how just how strong this being - the Opalescence? - is, and it's sinister potential. Overall, really well done!
