There was also IC in Paradise which ended up being abandoned, but that was his third game over 5 years ago.Anyway, at least in this case it's ICCreations, so it's fairly safe to say it's legit and not the first sign of quitting or anything. He's been doing this for his career for years now, has several completed games, and only — that I can remember — had one previous major pause. That was in maybe the latter ⅓ of F.I.L.F. But he's had his stride going again for something like 18 to 24 months or more now.
So yeah, I'd say this issue is legit, and iirc it was treated far more seriously when someone here posted him announcing it in his discord server, rather than this post.
