Why this game has been posted so early in development

As you may have noticed this game has been posted on this site very early in development. As the programmer on the team I would like to say that the game is maybe 40% complete. The core mechanics are finished and have been for a few weeks now. Now logic would be to continue moving forward in development, but we wanted to make sure the mechanics were as polished as possible for smooth gameplay. We believe that we achieved that goal pretty well and if you disagree please comment any issues or bugs that need fixed. We will start a list of bugs I guess. But, the important thing is now we can move on to music, polishing the story, and finally UI and overall make the game a more fun experience for everybody.
