Just finished your VN! I tried to play it almost exclusively at night to really understand the protagonist's point and view. While he is indeed a troubled and melancholic character, the sections in which he dedicated himself to reviewing visual novels felt joyful and fun, just like it must have been for him himself. Playing a VN about reviewing VNs was more enjoyable than I would have thought, so much so that I feel the concept could easily be extended (through a sequel, perhaps) to include newer releases. All in all a very interesting piece of didactic storytelling!
