YMMV / Blight Dream

• Breather Level: The days when Yuu is not around count as this, as the player can search the house undisturbed.
• Captain Obvious Reveal: The identity of the killer. In the intro, we learn that Michiru is an Amnesiac Hero who has a disease that gives her Anterograde amnesia, making her lose memory of every new day in her life, so she has to keep a diary to remember everything. Just a few minutes later, we learn that a Serial Killer murdered two people at the Mashiba hospital, and their identity is unknown. Anyone familiar enough with mystery fiction is likely to figure out the connection. Not helping is that the game tries so hard to make it look like her brother Yuu is the killer that it becomes obvious he is a Red Herring, and since Michiru and Yuu are the only main characters, there are no other suspects, making it even more obvious that Michiru is the culprit.
• Les Yay: Mirai gets kind of flustered every time Michiru talks to her. this can be interpreted in ... "curious" ways.
• Moral Event Horizon: Invoked by Michiru, who wanted to commit an action so horrible it would burn itself into her subconscious, and thus surpass her chronic amnesia. Thus she decides to kill her nurse and Mr. Hinohara. And in a way, it worked.
