The premise and the theming of this is so, so interesting, and I really enjoyed how information was slowly fed to the player throughout Clover's conflicting internal monologues. I actually wasn't expecting to feel much for not!Olive, especially after learning the truth, but after receiving the ending I got, I ended up thinking about Morning Sunshine's responses to Clover and the monster they fought earlier in the story... I started to feel a little sorry for them.
Additionally: I really liked the use and formatting of NVL-mode, and think it was very effective with the CGs you have!
