Game is kinda shit. A ton of the routes are really boring and dumb bad ends that feel like padding just to get to 100 endings. A number of endings are totally unsatisfying. Multiple eitos, all the buildup of him losing control as takumi kills himself then he just wins in the end anyways.
The game does a really poor job with its ensemble cast. So many characters aren't fleshed out in the slightest. Once you start to notice what i would call "Character trait role call" you start to get really annoyed by how shallow the characters are. Aside from a handful of leading characters most of the cast has a single trait and when something happens the entire cast just reacts to it with their single trait. Moko says something about wrestling. Shouma talks about how pathetic he is. Kurara says how superior she is, etc. It's disappointing that so many characters never get to show any other sides of themselves or grow beyond their 1 trait.
A number of things played for ebin reveals break down if you think about them at all. So they made false memories for the clones, and i understand they'd want them varied so that they can cover each others weaknesses but why in the hell are so many of them outright useless or refuse to fight? In the first route the vast majority need to be thoroughly convinced to join the fighting. Why DESIGN them to be like that? It makes no sense.
Beyond the mostly uninteresting cast and nonsensical story beats the gameplay isn't even very good. So many enemies giving bonus AP, gaining voltage for the sacrifice attacks, Nozomi able to heal fatigue etc, you can basically clear almost any map on the very first turn. There is very little challenge for anyone with even a small amount of SRPG experience.
In short, fpbp, it's shit.
