regarding aaaallllll of this, writen down by the dev, first, I'm absolutely impressed by the quality of the artwork, huge props to your wife, her talent is by far one of the best, specially taking in account that she's willing to draw sexual scenes for a game that her signinficant other is developing
second, is good that you are trying to make the MC more assertive, so far, he's sort of a goofball, hope to see more of this game
i would point out that the Celestina route... well, for some people is quite cringey and not arousing at all, would've been more fitting to put Holly's gramps and Celestine together, rather than the MC
okay, so far the game is highly promising, hope you guys get more backers and that you guys don't get burn out and drop the project, keep going, you guys are doing great
as side note, if you advence the Holly storyline until you reach intimacy with her, would be fitting to set up a conditional check, so in the main story
