I waited for this to go on sale to buy it because I wasn't sure I agreed with the price based on the simplicity that I observed from the demo. Anyway, this is an constructive, pleasant, satisfying distraction. Although, solving codes started to get less challenging as it went on, and not for the right reason. It looks like the developer gave up and ran out of creative ways to hide them halfway through and wanted to get the game out as quickly as possible. Also, please no more slide puzzles, sudoku is fine but something that requires such skill is crossing the line.
2026.7.10 Edit: OK the problem is the resolution setting. When you see that the interface is somewhat cropped, it's very likely that nothing reacts to your click. You can only press Alt+Enter to window mode and switch back to full screen to see if that works. Change the resolution in the menu to ensure you have the full interface. But even you do like this sometimes the click still doesn't work. Then a restart should do. It's still not perfect but at least playable now. I can alter the rating to 7/10. The art design of this game is quite satisfying. The puzzle is okay. It could be a decent game IF THE GAME IS NOT BUGGY. I played for about 10 minutes and unlocked 2 CDs. After that I can do nothing except clicking the start button in the game. No matter where I click on nothing reacts. I restart the game a few times and it still doesn't work. So now it is a game with potential but unplayable for me.

グラフィックや音や仕組みなどにこだわりが感じられる良い作品でした。 謎解き自体はそこまで難しいというわけではなく、だいたい3~4時間ほどでクリアできるかと思います。 とりあえず画像ファイルはじっくり観察することをオススメします。
