Comments on 7Days: Offline Mystery Story for Android

★★★★★ Nichelle MT · Aug 3, 2023
I've played this before & it's a unique "Choose Your Own Adventure" type story. Consider your choices wisely. (It does require a lot of reading but more like a comic book than a novel.)
★★★★★ Arum K · Jan 1, 2025
The story was quite short but fun and interesting plot, especially on first play. I like the game mechanics and aesthetics, also not fast-paced so despite the theme it still gives you time to consider your choice. I just wish it could be longer or have more choices. Good job dev!
★★☆☆☆ Aether · Oct 22, 2021
An okay game, but it's not like this is a masterpiece like some reviews are making it seem like. Unless I missed anything, there are four endings that are easy to achieve and the storyline and events are quite predictable. The dialogue is alright, but you don't get to spend enough time with any of the characters to feel attached. As the name suggests you're only with them for "seven days." Decent as time killer, but wouldn't recommend paying for it. Play the free version/find something else.
★★☆☆☆ Pandora Albright · Jun 5, 2023
I really like this game, but there seem to be some bugs. I joined hilde and argo, abandoning balsam, and on day 4 I woke up with balsam again. I seem to have triggered a different route, however it was not at all consistent even worse, later there was a similar but after balsam killed argo, I woke up on day 6 with balsam I would perhaps expect this from a free game, but this is very disappointing after paying for it will change my review if these things are fixed, or it turns out I am wrong.
★★☆☆☆ Anon Emoose · Jul 21, 2023
Decided to pass after I was faced twice with someone trying to kill me and the correct option was to give up and just accept it. Anything else and you die go back to the start. Much as I love backtracking and redoing entire portions, I'll pass. If I want to read a non-interactive story where I do nothing, I'll do that elsewhere.
