This is not even a game. There is no story line, or anything. Well you have a tiny description. But in the game itself there is no story. Where you used RPG maker and just put a few backgrounds that you drew. You said in your overview that you had more. But why not give the more so people actually could see what you have to offer.
The zero is for not having much of a game but wanting people to give you money on patreon. If it was just to say hey what do you think on what I did and say it is not really a game yet that would have gotten you a higher score or not even a comment.
