★★★★★ Suichie Wolf · Oct 21, 2020

I really really love this game. I did expect that it's Martin, but I'm still surprised. Love the part that you need to finish the other boys' path before unlocking Mystic Thief X.

★★★★☆ Shyni Sunil · Dec 31, 2021

Story's really good but it would be really fun if we could earn coins easily so I really hope you would do some change

★★★★★ Batrisyia · Jun 23, 2020

★★☆☆☆ Charalina SS · Aug 20, 2021

I was very excited on playing the game, and it has a very nice drawing but when I tried the game I can't even open it or start the game, im only in the main menu screen. I was really expecting a very exciting mystery game, I hope they work on this

★★☆☆☆ Nur Aida Nabilah · Jan 24, 2021

I can't play this game. When the first time I open it, I try to tap investigate but nothing's happen. And I decided to download it again but this time I open my mobile network, and can open it. It's like an online game.
