Keep in touch with your audience and give them clear signal that this is your hobby project and you value their input before they leave any rating etc. Side-project which doesn't make you happy sucks. You may be afraid of success or failure, but avoiding validation with users and constantly imagining what they might need more will make your burnout worse. I would hide non functional features and release now! Then do small update releases often - this boosts brain's instant gratification nicely.
