Literally no way of knowing with this dev. Whatever date they do give could be months or years off from reality. This dev is so unreliable with the info they give that if they told me the sky was blue, I would question it at this point, lol.
All I know is they seem to want to flesh out the roguelite mode more before releasing the full version. We at least have the shopkeeper and the companion gacha/system to come first. He said Shopkeeper was "Soon" about half a year ago, but was more specific with saying the companion banner would be next update. Maybe they will both be in it, dunno.
It's not exactly this specific dev, but more solo dev meets reality of actual game design.
Like, most "games" on here, aren't games.
TLDNR: dev kept adding content/systems you really need a team for, spreading themselves a bit too thin, for regularly releases every few months.
From skimming their patreon, it does look promising, but given their solo dev, and I assume they have a day job, it'll be a while.
Still fun to check in on when it does get an update though.
