As someone who also experiences anxiety and panic attacks, I definitely vibed with this game. One note I would add is that it might be good to add an option to make the sound effects less high pitched. As someone who suffers from sensory overload, the high pitched ringing from when the flowers bloomed made it a little harder to relax.
I appreciate the effort put into the beautiful visuals and designs of this game. It really has a calming and soothing nature to it. Not something I could see myself playing long term, but definitely a game I might keep in my back pocket for when I just need to de-stress.
