Guessing this is abandoned?
It's probably more like in that limbo state where the dev is active just enough on Patreon for it to not be tagged with "abandoned" but taking long enough for people to doubt any work is being done on it at all.
I've seen a few solo devs take a really long time to update and infrequent status reports but they eventually get it out. On the flipside, I've also seen ones that just kind of slowly ghost the project. That's why I'm considering this another one of those "limbo" status ones. Too soon to tell for sure. (Or more like we'll know when we know. The game is both alive and dead until either an update comes out or the abandoned tag is slapped on)
At the end of the day, even if Yuno gets an update out you should probably use that as a rule of thumb for how long he's going to take for each update. At this rate, maybe it'll be like 1 update per year if
we're lucky.
For a new game, that pace is pretty much just being dead in the water. Virtually dead. Which is fine if he wants to just do this on the side as a hobby but not really if he wants to do this full-time eventually.
