I like the animation about the step cousin. Also love the progress meter, when the game further develop you should add the MC progress meter, where is called 'Love Interest' and all the female characters, not sure what you'll do to the grandma, but it's your game, the MC will choose one girl cause all girls had option who the MC choose, and after choosing a girl to be a love interest, then there will be steps to further the relationship, but their also the option to have a harem progress called 'Polygamy Love' where the MC confess and date 3 to 5 girls, also the job mechanic should be category that is both safe or not safe, like working at a convenient store is a safe job, or a gaurd at a mall or street fighter is a not safe game, each different jobs had pros and cons. Those are my suggestions, but if you already had a plan for this game, that's fine, I just like to share my idea, anyway Be safe, Be clean, and Be healthy.
