Well to start off with, it is truly impressive to read that you are still willing to take up challenges and venture into the unknown despite the success with Mist and now Morn. I say this sincerely after having observed quite a number of developers who end up being held ransom by their earlier success.
I won't name games here, but I'm sure you know better. Lots of games made in the late 2010s and early 2020s that even till now are not completed - either updates have slowed to a trickle or the same concept / mechanics is constantly rehashed with patched on updates of story snippets, new locations or characters.
Having said that, I always advocate balance in development psyche. Indie developers ultimately have to do games they themselves like, otherwise a burnout is a when and not if.
However there are also no shortage of examples in developers who go overboard and just insist on what they want to do regardless of what the customers say. Such mentality is OK for a hobby but detrimental to run as a business.
Just pursue what you like, but also set up a mechanism to systematically collect feedback and collate data. Hopefully you can find a balance between passion and finances.
Good luck!
