the art of the game look really good but i think you need to make a dating sim with: ren'py and downloadable thats all what i'm gonna say good luck (:

if I could make a open world dating sim with renpy I would definitely do that 

To add to his Tip, there is a Twine format that can be found that works like Renpy but still gives you room that Sugarcube or Harlowe would give.
