If Capcom U.S.A. Inc. v. Data East Corp (the lawsuit) had gone in favor of Capcom, this game would not exist. They said it was "inspired" by Danganronpa. Bollocks. This is a note-for-note RIP OFF. Several characters are recognizably there, just with a few fundamental changes to keep Spike Chunsoft's lawyers at bay. There are clear analogues to Monokuma (I could swear they even got the same VA), the Ultimates, the Class Trial, and the executions. They have something that's Hangman's Gambit But Worse. They have the S-Link thing. A lot of the music is very similar in composition. The "make a comic" thing at the end of the trial is so identical to the ones in DR that they don't even give you instructions on how to do it. The fact that they put Kodaka in the Special Thanks SECOND after Rumiko Takahashi is quite frankly taking the p*ss, HAVING SAID ALL THAT, I enjoyed it. What it does differently is generally done better. They didn't have to set it in Japan or in the 1980s, because the developers are clearly from neither. It's painted-over Danganronpa, but the paint is mostly pretty.

I've had a certain itch while waiting for danganronpa 2x2. This fills this void perfectly right now. By far the most high quality danganronpa-like game on the market right now. It does feel too danganronpa though, but that's why I bought the game in the first place. 8/10. I see a lot of potential in this. I love the card battling mechanic.

I really like what's here, but the stuff ripped from Danganronpa THH is so blatant it's a bit insulting. If the whole game is using Danganronpa to prop itself up, I feel like it's more of an insult to the pretty well crafted narrative than anything else. It's impossible not to make comparisons when they are taking story beats / chars / concepts from a different game. But, the things that are new and original are EXCITING. Music/Voice Work/Animation/etc is fantastic and the original concepts are extremely interesting. Hope CH2 is even better.

Well, i just finished the first episode. And i can say that this game could compete with Danganronpa games. Aside from a few bugs, this game is REALLY great so far. From its Characters to Voice Actors' performance (Props to them, they really do a good job.) everything feels great. As far as i can tell, Development Team is doing their best to keep the game optimized and taking care of the bugs. Also even though we have seen one execution so far, the game seems promising about executions. (Either way, these will be better than Rain Code's ''executions'' that's for sure.) Most of the Mini-Games are also great. If you're a Danganronpa fan, buy this while it's on the sale. By the way, could Development Team tell me that when they are releasing the second episode? I can't just wait for it.

First Danganronpa fangame to jumpscare me in the middle of the night I think it deserves a recommendation just off of that Really though, this game is incredible for what it has so far. Voice acting is INSANE (Moichiro, Hiroshi, and Kaguya are my personal favorites), the card game gimmick is really fun once you get used to it, and the story had me hooked from beginning to end. I did have some small issues with gameplay (I dread the space invaders minigame), but aside from that this is a wonderful game that you should grab while it's still at the price it is now. You should buy it just cause of Hiroshi though
