Un peu prévisible la première enquête…

Trop évident

Response from developer

Merci pour ton retour, détective ! 🫶🏻 Le premier dossier sert d’introduction pour découvrir le téléphone et les mécaniques du jeu. Les enquêtes suivantes vont plus loin, avec davantage de fausses pistes et des réponses qui demandent de croiser 2 ou 3 indices venant d’applis différentes. Une nouvelle enquête arrive chaque semaine, alors garde ta loupe à portée de main ! 🕵️‍♀️🔍

It was very interesting but I was annoyed I had to pay for more than one game

Es ist ein Mega schönes Spiel schade ist nur das man nicht sehen kann wann man das nächste Level kostenlos weiter spielen darf oder ob das überhaupt geht. Wenn es keine kostenlose Option gibt wirklich schade

Vielen Dank für dein tolles Feedback! 🫶🏻 Freut uns riesig, dass dir Redstring gefällt. Gute Nachricht: Jede Woche erscheint ein neuer Fall, und der Countdown in der App zeigt dir genau, wann es weitergeht. Mit dem Pass kannst du außerdem sofort alle bisher erschienenen Fälle spielen. Danke für den Hinweis, wir schauen uns an, wie wir den Countdown noch sichtbarer machen können. Bis zum nächsten Fall! 🕵️‍♀️🔍

Needs work

I only did the first free case so my review is limited. But first impressions led me to turn down paying for the full version of the app. On the positive side, I liked how you could pin clues to the board. The phone apps for browsing were laid out well. But I found the questions to be worded in a confusing manner and once you entered the correct answer, the next part of the story flashed on and off the screen so quickly, you had no time to read it fully before the next question popped up. So the whole time I was playing, I barely had a grasp of the storyline or what was going on. Even so, like most games in this genre, the suspect became obvious very quickly and it was just a matter of trying to answer the questions correctly, which wasn't always the easiest thing to do. For instance, if asked for a time that a certain event happened, "2:00 pm" will be rejected but "2:00" will be accepted. Oftentimes, it's just trial and error trying to figure out the wording that will be accepted to move on. For these reasons, I've decided it's not worth paying the $20 for more cases so I'll be deleting the app.

Good game but…

The game is fun and entertaining, but after you complete the first one, you have to pay for pro to do the rest of the investigations. If it wasn’t for that, I would 100% recommend it to anyone who likes investigating.

Response from developer

Thank you for the kind words, detective! 🫶🏻 We're really glad you enjoyed the first investigation. The first case is free from start to finish, and the Pass is what lets us keep building new ones. Every case is hand-made, with an original story, real evidence, custom photos and translations into 8 languages, and each one is tested continuously before it goes live. A new case lands every week, and the next file is already on the desk. Hope to see you back on the board! 🕵️‍♀️🔍
