I might write a longer review later but this "game" should be better marketed as a visual novel given how there's barely any gameplay. I would rate it very highly as an exploration of contemporary social issues in Japan (racism against Zainichi Koreans and Chinese, idol culture/hikikomori culture where lonely young people put all their hopes in parasocial figures, corruption and hypocrisy in law enforcement), which makes it very similar to the Yakuza series in terms of topics tackled, though the Yakuza series actually manages to have somewhat compelling gameplay in it.
I think the dev has also realized how he likes writing stories more than games, since the new casino arc is literally entirely a cutscene and features some overly complex baccarat cheating that's straight out of the Kaiji manga + the overall "mafia conflict disguised by gambling" plot that's straight out of God of Gamblers (1989 starring Chow Yun-Fat and Andy Lau). The chigyus are also pretty much just a mockery of the playerbase of the game (lol) as well as the dev himself, given how one of them is a failed doujin game developer and the other is a traditional martial arts otaku... Yanikas is clearly the dev's idealized version of a man, a gigachad mafia boss who is a judo expert (?) and every woman is obsessed with having sex with, while the chigyus are his way of returning to reality (especially with the tongue in cheek about Luffy and his "Haki").
The problem just lies in the gameplay being horrendous and just straight up detracting from the beauty of the plot and art. Hopefully the dev actually decides to just release this as a visual novel instead, and gets to focus on writing the story he is aiming to.
