I'm gonna share here too that the emotions in this game really hit home for me personally so much, thank you for sharing this!
The way those dark ugly thoughts can just stow away under your skin like seeds, and then bloom late at night when you're alone with your thoughts - the use of flowers in this story I just love so much, it's so well-done. The art too fits the imagery, and the sound effect got me so well too - it's an unpleasant feeling, and you conveyed it really well!
