I would suggest a game dev forum instead. Like TIGSource for example (https://forums.tigsource.com/). There are others as well of course, so a quick google might help you further.
Another thing I would do is add more information about the game itself. A little bit about the story, and how the map itself needs to look (orthogonal, side view, hexagonal, isometric, what kind of tileset(s) etc).
