It's a bit glitchy.
An additional clue shows up when I check the clue in the desk.
When I got the order right for the students, food, zodiac, and hobbies nothing happened. I undid everything, checked your walkthrough, and placed them in the exact order I had them before and THEN a cutscene happened.
Items appear for a split second when you switch scenes.
Wish the chalk would disappear once messages on board show up.
Wish the bento heater wouldn't activate if there is nothing in there.
Other than that it was a good escape game where I needed little help. It was a nice brain buster. Good challenge, not crap like other people are claiming.
