This is the gold standard of what a first release should be in my book. It introduces us to the key characters, nicely sets up the plot and gives us a good amount of content. Few first releases are this long and even fewer are this good!
The game looks great, and as one expects with Lockheart, it's really well written and genuinely funny. I love seeing the MC's character development from the previous game, that kind of thing is so rare in games like this. I'm also really excited for the new characters that have been introduced, I especially like Suzi, which I did not anticipate. The music and sound effects really add to the experience, including the lewd scenes. It's also not necessary to have played A Petal Among Thorns to enjoy this game, though having done so will add to the enjoyment of some scenes.
So yeah, I really like this game. And it's from a dev who has multiple completed games under his belt and who has a track record of fairly consistent updates both in terms of timeframe and quality, so I think it being completed is a fairly safe bet. I can't urge everyone to try it enough!
