Yeah, it's a popular problem. I know many people (I myself am such a person) who are making a game and reject it for some reason. Sometimes we also abandon the incomplete project and immediately get down to another game, and then we are going from the second project to the next, until it all will be abandoned and incomplete. In your case there is nothing to worry about that your project is bad, because it isn't - it is a really great game. Unless you do not like your project, because you are simply bored with it - the creation of the game must give a fun for you, so there is no point to coerce to it.
And to the abandoned project you can always go back :]
