Finally, I found a classic puzzle game with no story or anime, just puzzles! It is similar to the room series. The disadvantages were it is a little complicated and tedious, cause the game is full of 2d pictures and you need to tap everywhere to find useful things.
Although I can pass it (sometimes need help with the walkthrough), it was fun and spent about 2 hours for me. I like the game, puzzle fans could try it.
