Keep working on it gizmosan, it’s a great learning experience & it looks really good. By the way, I know what you mean by time issues. lol
If dropping a stone doesn’t make sense for a regular game you would like to play normally, try to still use the concept. Just from the way it looks, I’d say it’d make a great strategy game.

None the less, keep up the good work, I wouldn’t totally scrap idea. good luck
