Hello, there! A whole lot of my characters (not all but a GREAT majority of them) are on the ace spectrum. Some also on the aro spectrum. In all of the games I've released so far, there's AT LEAST one ace character that is important to the story.
In this case, Aspen (the MC) is graysexual while Crowe is demisexual. The thing is that the topic of asexuality and/or aromanticism doesn't always come up on my games. For instance, in games like Petrichor, Hummingbird's Crown and Azure Flame the representation is "more obvious" but not all of my games have scenes where they talk about being ace and/or aro.
Killer Trait will have some talk about that in some scenes but it's not really the main focus of the game.
If your worry is about finding anything NSFW or spicy in my games then don't worry, I don't write NSFW nor really like writing spicy stuff either. At most, there's flirting and kisses, but I never like to go beyond that in my stories because it's not something I enjoy writing.
Still, once again, it really depends on what experience it is that you're looking for when you say you want games with ace/aro MCs and/or LIs.
Hope this helps!
