Here's my review of the last update for those on the fence of whether to try it out:
So I played through starting from Act 2 Chapter 1. This update was really just a lot of polishing. Especially the hint system is now good enough that you don't have to read through every text to know what to do. You can pretty reliably skip through everything and then look at your hints to see what needs to be done next, which is a blessing for those of us who've played through this game in the past.
Furthermore, the most annoying part of the last update, which was waiting 1 week for Hagrid to get the skirts quest done, got removed by you being able to simply summon him by owl, this makes the last parts of the game not drag as much.
Finally there's a few smaller additions: A small date with the main girl, which is really more just an introduction to the dating system in general, as its just asking them questions about their goals etc. and a few shower voyeur scenes that can be accessed by getting a potion by Snape that makes you invisible and then searching for the girls in the morning or evening in their respective dorm showers. These scenes are pretty small though and only complete for Luna and Daphne. They feature them masturbating in the bath. You only see them from behind though and its just their regular sprites being reused, so it's honestly not that exciting.
Overall I would say this is a pretty good update... if it had taken 3 weeks that is. That this kind of update takes them, a team of I think 5 (?) members more than 2 months (last release was mid july, I checked) is quite honestly ridiculous. Honestly since Joe Banks has joined the team, the game has finally been going in the right direction, but the development speed is still ridiculously slow. I very much feel like the "core" part of the team is taking a month long vacation after every update and then doing 10 hour work weeks till the next. Not that I can blame them with so many patreons just sucking it up.
Also, as someone else already mentioned, the missing mini games from the last update that 'barely didn't make it in' are nowhere to be found? What the hell?
TLDR: If you want to replay a less buggy 0.6A go for it. If you're expecting new content, you're out of luck.
