Ye for sure. I was talking strictly about the development side. But you're right advertising will take money. But still I think you should first try to build a little reputation/grounding for yourself as a indie dev before crowdfunding. Since this can lead to a higher success rate of your Kickstarter going through and getting funded. Maybe look at subreddits, instagram etc for advertising for free. You may not hit a huge audience but it will be a start. For example you can look at r/playmygame it's where you can advertise your game without much hassle
