One thing I like about this game compared to so many other games here, is the sex and sexual scenes aren't ridiculously contrived. Yes he has a lot of sex, but it's mutually consensual and realistic in the context of each interaction.
So many games here are about some creep trying to coerce women through subterfuge, "Oh my pee pee hurts like this, you have to help me", or people "accidentally" walking into each other in the bathroom and then it evolves into dick sucking.
In BaDIK the mc is open about who he likes and what he'd like to do. It's refreshingly normal in a genre overpopulated with fucked up perverts.
Sure the mc can often look up girls dresses (and I find that more childish than DIKish), and Jill has a couple accidental tits out scenes and there's that accidental groping in the shower, but it's far from a theme running through the game (and given Jill's naivety in sexual situations, some minor contrivance was required to keep the player interested).
But while the formula is simple, i.e. let a girl know you're interested and see where it leads, each of the girls' progression is still significantly different, and in that sense, somewhat realistic (Bella is attracted to the mc but isn't sure if it's a smart relationship, Jill likes the mc but is afraid her lack of experience will be embarrassing, Josy & Maya are keen on him but don't know how it will affect their existing relationship, Sage just wants to fuck, and so on).
So yeah, instead of raping girls in their sleep, setting up spy cameras in the girls' bathrooms, finding potions to make girls like him, the mc simple tells them he's interested in them. It's so radical!
