Rather than running a kickstarter, have you considered maybe setting up a patreon or a ko-fi? You could still offer rewards to the people who support you through the development process - backer updates, periodic releases for the backers only, name in credits, etc .
While it might not net you the same up-front amount as a kickstarter, it would give you some money to put toward things like your artwork, etc. and hopefully you wouldn't have to give up the game or compromise on the level of quality you want to put out.
