You're wrong. He's been sitting on the update for months, likely bidding his time so that he can deliever 2 updates per year and milk this as long as he can, for years, until people grow a brain. Hook and fish patrons, a couple wallpapers to "keep the dream alive" and he's all set for a couple thousand free dollars per month. I mean, half the work is done, the story is set, the "waifus" modelled and most the of the same CGs and scenery he keeps re-using are there. Its not like its even hard to code the game, its not exactly choice driven. Most of the work comes from setting renders and animate scene, which takes a long time, but certainly not this much especially for what will be like an hour (if even reaches half of that) worth of content.
