I remember the announcement and waiting for the first episode. I had asked Casey whether he'd be using what is considered "modern" C++ (he doesn't), and whether he'd be developing in a test driven development style (he doesn't). His response was practical and honest. Like his programming. Highly recommend watching one of his videos.
The final video available is titled "Handmade Hero Day 667 - Simplified Tile Occupancy Checking", and ends with Casey explaining his plan for next week's session.

> Handmade Hero is currently on hiatus. The original set of daily source code archives can still be purchased here for those that are trying to follow along with the original series. You can also follow Casey's current programming courses at computerenhance.com. > We hope to have more information in the near future about whether we will resume the series or replace it with a newly-designed one that better provides the educational benefits people ended up wanting.
