Not trying to defend the Dev, in fact, one of my comment was removed because I was "rude" to a spy who reported this place to the dev, but I think we just have to accept that the better the art, the longer the update/shorter the content in updates.
This is not one of the games here that was made with AI art, Honey Select or Koikatu and the art is top tier amongst the hand-drawn ones here.
For instance,
My Pig Princess which is probably the peak in art style takes at least 5-6 months to update, with each update being 30-45 minutes in content.
So, my advice is too probably come back after 3-4 updates and not follow it too close unless you will just be disappointed.
