An enjoyable horror experience that nicely builds up the mystery and suspense of the story. I have a full playthrough if anyone's interested:
The CG art and writing are great as always, and no doubt it works well when it's a visual novel/adventure game. I like the chemistry between the main characters and how the climax is revealed.
However, the Diner Dash-influenced gameplay sections are definitely rough. I feel as if the limitations of RPGmaker forced some strange game design choices. For example, the player isn't able to stack multiple orders of the same type, so you end up losing precious time waiting for meals one at a time which makes the later days more difficult than necessary.
Overall, it's not a deal-breaker, I still had a good time!
