Hi Kevin, thanks for following up...
It's still going... and slowly each piece gets added towards a build that would be ready for sharing, in some way, in some format... I inherited a MacBook Pro just before Christmas, so at some point will see how it cross compiles for Mac as well as the current Windows Build

The core game is in a playable state as it is now, but still quite a few rough edges and needing a menu system, help system etc.
As for how long it will take, I hope you will forgive me for not wanting to mention a date, since this just creates expectations that need to be looked after. It remains as a hobby that fits into the idle hours of life, and how many of those come along in any given week or month can be unpredictable

I had thought it would be done in 2018, but here we are still...
I'll come with more concrete details when I get that confident feeling that completion is a few weeks ahead.
All the best
