Yep, that's another game I've had my eye on that hasn't gotten an update in 2 years, another one was Heros Harem Guild. Anyway, as far as I remember... in June of last year, there was an idea to launch a new game update but in practice it wasn't really posted. I've been waiting for version 0.3 since then.
Bah, I'm not talking about that man! The problem with Heros Harem Guild was that the DEV always got the ETA wrong for the game, consequently leading everyone to think it was just a SCAM. As a member of the F95.zone Forum... that game thread turned into a Toxicity pit.
And to make matters worse, neither the DEV nor its Patreon were updated, and getting to know the game was difficult. Practically, we spent 1 or 2 years without any news about the DEV and about the game, just milking the donors!
When we finally heard about the DEV and the Game, it was supposed to be a Christmas event that was supposed to arrive at Christmas last year... but in reality it never arrived, or if it did it was as seasonal content in this last update in late April and early of May. Anyway, I know the game recently updated with a seasonal event, I'm following the DEV but Heros Harem Guild has a very problematic development.
That's why I mentioned it here, but unlike the Heros Harem Guild DEV, the EroSekai: School Life DEV has been updating its patreon since March, even though we've been waiting a long time for a game update.
