Holy shit this has to be the best H game I've ever played, and may be one of the best games I've ever played period. Might sound insane but I didn't even get off once to this game, and I was skipping through the sex scenes just to get back to the gameplay.
Visuals - extremely stylish, just look at the images online. Even outside of an erotic standpoint, the art and pure style is fresh and captivating
Characters - the full cast of characters is extremely compelling, with full voice acting for named characters. Originally, I expected myself to be skipping through the dialogue for the male characters, but they are as compelling as the female ones. I think at the end I had the highest feeling with Zappa (a burly biker guy in sunglasses) instead of any of the heroines. Shoutout to Shimazu for being the gigachad/strict dad of the show - his lines are cold af too (got shot to pieces then commented he"liked having a breeze on his insides")
Sound - The voice acting is superb. I must admit there are some that are annoying if they speak too much (Alice...), everyone was acted with passion. Characters like Kirakira and Torataro really feel like your old friends after you get to hear them speak enough. In addition, the soundtrack is also superb, and the battle music really reminds me of the street fights from Yakuza 0 (iykyk)
Story - Decently well executed story about an evil corporation controlling society, being a metaphor for conformism. Nothing spectacular, and the moral greyness of their "hustling" could be explored a bit better. They just handwave it by saying the victims are part of an oppressive society so they deserve it - it would've been better to focus more on it. Nonetheless, the villains are very hateable (beating Kuina after becoming vastly overlevelled had me cackling) and the final boss fight was satisfactory, if a bit underwhelming due to my over-preparedness - the final boss's ultimate move, a literal ICBM, did around 5% of my party's hp
Gameplay - the gameplay is also really fun, and reminiscent of Darkest Dungeon minus the permadeath elements. In fact, I had been looking for something like this, since I wanted to find a game with darkest dungeon gameplay without the brutal difficulty and with party members I could bond with. Dohna Dohna perfectly fulfils this niche, but would've been made better with the "movement" included in moves as well like in darkest dungeon. One downside of the gameplay is that it is quite grindy - finding weapon parts is quite RNG even if you spam the maps that drop them. On the bright side, you don't need to max out all weapons to easily dominate the game (read above about the final boss fight), and I never even used a single consumable item so you don't have to farm for those either. Money is scarce at first but once you get "matching" going it's basically unlimited.
Overall, 10/10 and I would definitely recommend this to anyone, even if you aren't looking for an eroge
