... I'm happy to see a game jam where the rules treat adolescent sexuality/affection sensibly and sensitively instead of just having some blanket ban like "no relationships between characters below 18, period." Sexualisation of children is a serious problem, but so often, content hosts seem to fight it by taking the safe option of just banning anything that implies that people under age 18 are capable of sexual or romantic feelings. I wish it weren't so unusual to find a place that's willing to grapple with the complex, messy reality of what being a teen is like.
Don't think I'll make anything for this jam (don't really have any ideas that would work with your theme), but I want to thank you for your sensitivity in stating the rules, and fully support this theme.
