[NON - SPOILER]
I like the concept of the game, detective novels are always my cup of tea :) . Love the art, especially the cover art, the character designs and the music are nice too! It's a calm and simple game.
The story is ok, we didn't get to have much choices but that's fine for short visual novel like these. I noticed many spelling mistakes that can create a quite bit of confusion (For example "Get alone" instead of "Get along") but a small detail that is my personal favorite that, I get to learn more about some interesting facts between chemicals haha.
Is the case predictable? Kind of. My first suspicion toward a suspect is turn out to be correct. But I think that's for the better, if the case is longer and more complicated the game would have taken much more times and efforts. Although I can assure that it's still going to turn out amazing either way!
From what I'm seeing there isn't anything too special or that stand out, but if you up for a quick short nice story then you could spend a few min trying out this game :D
