The game frankly starts in the oddest and least gripping manner possible for a mystery game , but it does indeed get a lot more exciting in its second half. The issue is that it's so centered around its gameplay system that the scene-to-scene writing and characters are overall too plain and hard to get invested in for a murder mystery.

Each chapter follows the format of something happens to someone --> protagonist and a few witnesses have a discussion on what happened --> everyone votes on who they think did it. The way each chapter is so stiffly structured makes the unfolding of events in the story a bit too convenient for the sake of gameplay, but I was pretty hooked in the last few chapters.

The main ADV game system is the discussion, and it's quite unique for a mystery ADV since every time you ask a character about a piece of evidence or someone else's testimony, or try to piece together the answer to questions by combining evidence and testimony, it takes up time. There's only a limited amount of time to discuss the issue before having to vote on whodunnit, but in practice you can just savescum if you're stuck. Somehow I found myself stuck in the situation where I knew what happened already but I need to find the exact 3 pieces of evidence to get the protagonist to figure it out quite a bit.
