We get into this debate every update (which means yearly I guess) but amongst all the developers here who very rightfully gets called out as a patreon milkers or borderline scammers *cough* School of Lust *cough* I really don't find Irphaeus to be that bad. I think he delivers what he promises, updates actually have quite a lot of content. While I don't find him a super skilled writer I think he's genuinely good at creating the kind of scenes or setups you'd expect from an eroge, I find myself pretty enamoured by these characters. I think it makes sense updates would take this long if you're an one man team (yes, even if it's all Honey Select).
Now personally I wouldn't want to pay the equivalent of a AAA title each year for 2h or so of gameplay, and I certainly would be wondering why he's starting a second game (iirc) when this one's still far from finished. But it's not like it's blows my mind like people still supporting unplayable messes like Spooky Milk Life or My New Life.
