What a wonderful little diorama!
Your models all look fantastic, and your protagonist's room feel like an authentic, lived-in space. It was also very cool that you allow the player to rotate, zoom, and pan around. Even though the gameplay would work just as well in two dimensions, you went the extra mile to really bring it to life.
Your hand-drawn portrait looks great as well, and the dialogue is nicely animated and easy to click-through.
There is some really strong visual imagery in the writing, but there were a few places where it was a little overwhelming. Those first few paragraphs are so dense: a yawn pulls your mouth, your brain itches, your brain is jostled by a sharp beep, you are pulled to your feet by numbness, etc. You have found lots of cool ways to describe waking up, but my own brain could have benefited from some straighforward descriptions for balance.
The music was good - it would be cool to hear a version of this song that uses some more acousic-sounding instruments, only because midi gets a little grating over time, and the melody itself was lovely.
You did a great job of demonstrating your character's relationship with ADHD through their descriptions of the world. I am not so familiar with ADHD, but your post-game message helped reframe the way Ila organizes her thoughts. Well done!
I hope my feedback does not read as overly critical! I am so impressed with this final product, and I only have so many thoughts because it was such an engaging experience overall! I am very excited to see future Acorn Jelly games, and I am excited to play Celestially Yours in the near future too!
