Images look decent but HTML? Pass.
Quite unique at that, imho. I don't like many SC games and this has been one of them for ages. Always considered it a text-based game with images, not a visual novel - and I admit, don't often play these. The writing is very good, goes into detail and creates an atmosphere that helps one get immersed quickly. Add that you have a mainly story-driven game that still gives you strong free-roaming. It's one of the best achieved html games I know, for sure.
What got me thinking is your mention that it’s been on tfgames for years, yet the thread on f95 was only yesterday created
This suggests there are likely many good adult games out there that aren't on f95 at all..
Which sites best complement f95?
TFGames is rather specific to an audience that enjoys transformation themes. This was probably one of the few very popular games there that, although featuring it strongly as one of many optional paths, is not about m2f transformation, and lets you completely ignore it without seeming like you're rejecting options (play the logical choices for a dominant MC and you'll probably never be confronted with it).
For the most part, games that you find on TFG that aren't here, will be focused on trans MC and thereabouts. It does have a powerful advanced search, which I use complementarily with F95's. Different approaches, different options, helps narrowing down searches if you're obsessed with a particular subject and don't care to put time in downloading and trying out games that you don't mean to play.
I sometimes use lewdzone.com because, like F95, it lets you combine tags and they often tag games differently than here, but the games you find there are 99,9% likely to be uploaded here as well. Itch.io may have a few more titles and a greater variety of formats. You can also try the Visual Novel Database at vndb.org, lots of tags to choose from as well, probably many older titles that never were or will be uploaded here.
