Only one episode is free, the others must be purchased individually (it gets expensive!) I found this game plays best on tablet, cause some scene differences are nearly impossible to see on a phone. Also, the English translation is a bit poor and that makes it much harder to understand the story and therefore identify the criminal. Good concept & art but flawed execution :(

Great art style and story telling! I've only completed the first case so far but I'm enjoying the game quite a lot. They did a great job that even after all the evidence was gathered it wasn't immediately apparent which suspects could be ruled out. The questioning was a lot of fun, too. The game also doesn't require you to spend money or watch 20 ads to be able to progress. At least it hasn't until this point. I watched a total of 3 ads to gain hearts so far and made no purchases.

This game is cute and fun. You solve the mystery by choosing the suspect and evidence you found that best explains the how and why of the murder. This was enjoyable! My biggest gripe is the way to get access to other chapters. I do not mind ads because I don't have to pay to play. However, this game is excessive. I have to watch 20 ads just to get to the next part which takes less than an hour to finish! Not worth my time or money. The current lives system should be the only revenue method.
