I would highly recommend you not quit but perhaps see if there are any more flexible working arrangements you can come to with your current employer.

Perhaps you can go part time or take 3 or 6 month (unpaid) leave?

I wish you all the best whatever you choose to do. Make sure you post an update when you have something to show.

Also maybe go the 'devlog' route and document the process on YouTube and Twitch as those are pretty popular right now and is a good way to gauge interest and feedback for "free".

If he's not too tied to his job, leaving and finding another one in 6 months shouldn't be a big issue. Whenever I start looking, it takes me around a month to get a new gig.

This is not a normal time though and who knows what the job market for OP's area will look like. Potentially there will be lots of people looking at not too many open positions.
