The gameplay is alright, in the beggining it's fun but over time starts getting really repetitive.
The story, like most danganronpas, gets really cool towards the ending but the majority of the game itself is pretty boring, except some moments here and there where you can empathise with the villains.
Now, the thing that made it so that i couldn't rate this game like a 2.5 or something is that it has a pedophilia problem. It's not even that the community sexualizes a 15yo girl or whatever like in most anime, it's like....a character is almost explicitely a pedophile and one of the villains is a little girl (arround 12) and the game has some weird camera angles that expose her in a weird way and in her boss fight she loses clothing the more you hit her (no actual nudity but still).
