Hi hi so to answer your questions one by one. The game is not just about dating guys, it's about understanding how this world works by seeing what each of your friends have been through, which just happens to be potential lovers. Which explains why there are currently 14 routes and not all of them are dating. 

The reason why I use RPG maker instead of renpy is to give players a unique experience in roaming and interacting with NPCs. Yeah there aren't a lot of options of where you can go because this IS still a visual novel and not an RPG. You have to follow the paths of the story, but at least you can talk and interact with stuff while earning achievements. 

The reason why there is no battle system, is because the game takes place in a time of peace where fighting is no longer necessary, as shown in some books in the library. Also because not all powers are used for fighting, such as Marlin who has translating powers. 

And don't worry this game ain't just about dating gay boys, it is a hell of a lot darker than that which I will show in the future. Also the main character is neither good or bad, but you don't choose to be either, it's more like seeing through the eyes of different sides of the coin and you decide what is good and bad. Hope these answer your questions!

And one last thing, my VIP perks is that you can have your character inside the story, so you can be as bad as you wanna be in the game
