shitpost answer: nah u gay lol
Serious answer: Max is still designed to be cute and feminine. The fact that you find them arousing is because you're seeing those qualities. Everyone can stop worrying that they're gay now. (not trying to sound combative, just saying)
Vaguely-related-rambling-directed-at-nobody-in-particular: When people are complaining about there not being other games with art like this, I think it's that focus on cuteness that people are referring to. Or at least it's what I'm referring to.
I'm not too good at explaining this, but in my experience, the vast majority of games that come out with female MC's go for significantly sexualized characters. Even if the art style trends on the cuter side (e.g. something like Atelier Tia), characters still tend to have above-average tits and ass sizes, and wear clothes which are overtly sexy and/or exotic. Few games go for smaller proportioned characters and more common girly clothing choices unless there's an additional reason to. Usually, that additional reason is that the character is a trap, genderswapped M2F, or a loli (and even then, the genderswap option is usually limited to text-only games like Newlife, where there's a lot of options that frankly don't change much). Basically, unless the game really needs to sell the character as young or feminine, these attributes are usually ignored in favour of big tits and skimpy clothes.
I think that's why so many people (me included) seem to be expressing frustration in this topic. Yes, there's plenty of female-protagonist games in this vague genre. No, I don't want this game to be altered to my tastes - this niche is catered to less than most of my own, plus I like the game anyway. But... I mean, there aren't many games with cute, non-hypersexualised main characters, and I don't think there's many other ways to say "Hey, we want more of this sort of thing!" Just kinda shitty that it comes off like complaining about this game.
