At time of writing this post I'm working on another romance game called Heileen.
But what are those kind of games? very popular in japan but rarely translated in english, they focus mainly on the romance / relationship aspect. Some of those games even contain erotic content, but of course I won't be able to include that in any of my games, since I want to sell to everyone

They're mostly adventures but also contain many elements from other genres like RPGs, simulations, and such. Some have mini-games inside them, other have a real combat system, and so on.
