Speaking as a fellow developer, you're right not to rush it out the door. It will get done in its own time. I don't know enough about indie marketing to know if October would be best for your game, but I know your game will be better by being able to breathe and spend time polishing it. Good for you for not publicly posting a release date. I've seen too many quality developers get tanked by doing that to themselves. Just wanted to tell you that you've got this, and I'm eagerly looking forward to the release, when it's done and ready. <3
