He says he owe the supporters one more update and then will throw in the towel unless his support level goes up, then he will continue making the game.
I don't know if people will support the project if there's currently nothing to show for it.
People will need to know you are not going to disappear for nearly 2 years and then pop back up and release 1 update.
rainces will need to be more active and give out news about the progress of the update more often, if he wants to build back the support level he had before.
The ball is in his court, be it throwing in the towel and calling it a day, or put in the work and build back the support. It's entirely up to him.
