on my to do list: making girls for my VN that have normal breast sizes instead of J sized breasts on a teeny tiny body. I mean, I might have some busty ones too but c'mon.

More than just that 'one flat chested character who is self conscious'

I don't normally have an issue with idealized bodies, but recently all I keep seeing is anime heroines with impossibly enormously huge breasts

things I am deciding about this so far

Protagonist who's not a clueless airhead but also not ridiculously aggressive 'strong!' either.

One character will be your bromance character, who will commonly be present and always important to your character but never romantic except on his specific difficult route

because bromance

megane all errywhere

one character will be hikkikomori because I say so, and there will be at least one or two 'older' characters, though the protag + most routes will probably be in their twenties?

There will be a cutie pie because there should always be a cutie pie. He won't necessarily be the stock shota though because that would be kind of boring

I am looking up VNDB tropes to decide which characters I should have.

it will not be stat raising because screw that noise, that's hard to program.

I'm not sure if there will be many support characters, because support characters inevitably end up with "why can't I date that" syndrome

Not every route will progress at the same speed or ease

eventually

there will be 3P/harem ends. Probably harem first because that's easier to do than dynamic 3P modes
