this is actually pretty interesting so far. I hope it stays that way.1 found this helpful
was browsing steam sales when i came across this, impulse purchased it because i love danganronpa and similar murder investigation games and the idea of a "card battler murder investigation" intrigued me. best impulse purchase ive ever made! the voice work is amazing, the writing is both hilarious and compelling, and all the characters are their own flavor of interesting without feeling forced or too cheesy. gives me the same feelings i had when i first played danganronpa all those years ago. HIGHLY recommend if you're a fan of murder mysteries/the danganronpa format and i can't wait to see where this story goes in future episodes!!!!!1 found this helpful
Its like Danganronpa was transferred over to a graphical style I preferred. get it.1 found this helpful
LOVED the story, such a fun and interesting way to stray from the beaten path of dangan games. so invested in the characters and the plot, CANNOT wait for episode 2!1 found this helpful
So this is my first review. After reading some other reviews. I really do like the first chapter. I think the characters are fun. But I am with some other people that a little too many of them have antagonistic attributes. I just hope they become a little less so if the main character is not the main culprit moving forward. But two other things a lot of the minigames are kinda boring. The card game most of all. It dosent feel great as a deckbuilder from a person who loved deckbuilders. Its just kinda of rock paper scissors with card and four options. Know what made me give this a postive review is simple. The intergration of dandanronpa and horror. Those parts were the clear highlights of the game. I even have guesses about future events that ill save for when the game is completly out. So devs if youre reading this I hope the futre chapters have more care put into their minigames. The card game has potential but it certainly needs to be find tuned in a way where its not a waiting simulator basically. The best deckbuilders are all about synergy and having the chance for you to win on the spot and your opponet to do the same. More ways to control your draws. Because the most importa…1 found this helpful
