This is amazing! I love it so much. I like how Yumeko has 3+ voice actors. It really adds to the drama of the statue ending, when the speaking voice switched. You also adopted the myth well, in my opinion. Like how Pygmalion in the myth formed the statue, chipping away at the stone until it looked how he wished it, The Doctor also took away whatever he found unattractive. Unfortunately, it isn't just marble or stone that he was chipping away. It was her code, her being, her true personality. I think that's why I feel the saddest for the statue ending.
I got the happy ending first, which was nice. The doctor was being really annoying, and seeing his downfall was cathartic. Speaking of, the doctor was really detestable. I just disliked him every time he spoke. His voice actor did a really good job, to make me detest him so much! And the writing for him was awesome too! I especially liked Yumeko's thoughts on everything the doctor said. It made me chuckle a bit.
I also love the visuals, especially for the statue ending. The last sprite of yumeko in the computer made me so sad, with the fingerprints on her neck. Getting that ending really pained me, and i think the visuals really helped with that.
All in all, 10/10
