Eh, I wouldn't really be all that perturbed if there was never another update. I also wouldn't be surprised if he just popped up again soon with a post. I think this dev has his own circumstances so I can't knock him. But for sure, a few updates every now and then would be nice. Even if it's just a "too busy with life but I'm alive" kind of thing.
But I think my ambivalence stems from me just losing interest altogether in VNs. It really just feels like there are a few good ones left but anything still updating and worth playing are all the ones that are starting to take a year or longer.
And don't even get me started on BADIK, DPC's got a plethora of problems and the long updates are just a single symptom. But it's too hyped to fail at this point so if I'm still around in 5 years, I'll just be waiting for everyone else to realize it jumped the shark.
