This VN strikes me - in the best of ways - a shorter, lower-key, and more intimate version of the obscure PC-98 VN Mirrors. The deliberate limitation of on-screen colors is masterfully used to help convey the story's ever-foreboding tone, as well as provide the sharpest photorealistic images at 640x480 I've ever seen in a modern RPG Maker game. The dialogue pacing is excellent, not to mention acts as a sort of silent voice acting by stopping, starting, and varying speed like voiced dialogue would. The characters are well-written. Overall, fantastic!!
While I do have some nitpicks, like the "Fast" option speeding up all dialogue, unread or not, I suspect it's merely due to the third-party plugin chosen and not a willing choice by the author.
