i feel that drawn art used in video games is far superior to 3d models because each person's unique style adds a love to the game that doesn't exist otherwise. extreme effort was put into the animation of all of the predators with stomach sizes that scale to how many they've eaten. every single character is cute and i love watching all of them inhale the little humans. the gacha style is a very good choice because not only does it provide a ton of variety, you simply don't use characters that you don't like. i'm personally not a fan of the mushroom or the jiangshi so i just don't use them in gameplay.
honestly the fact that it's available for free is an absolute steal because this feels like a full production game. open your wallets and kick the developer a few bucks, and hopefully we can goad them into making more of these kinds of experiences.
my only complaints are minor. solphie's stomach should make a stomach sound instead of the cartoony boing when prey reach it. some text isn't translated well (in rare cases it's nonsensical,) and english text goes straight off the screen sometimes because it's too long. japanese seems fine though.
