It has a fair amount of content and it has enough to be an experience and enjoy it, but yeah still fairly unfinished mate. The dev has a lot of content planned, and is currently focusing on exhibitionist content with some characters. There's only one out of four flatmates, but Robin has a lot of content to enjoy, especially if you want to play as a slut. The main quest has at least one major area to play and enjoy. There's 3 jobs: Pub, whoring, and cleaning implemented with varying degrees of content, cleaning itself has 2 places where you can do it. You can also attend school, with the dance club having a quest line with an offshoot photography one. There's also playing with the soccer boys, you can convince Robin to join in too. She might also hang out with them on her own, but you can help her break out of her shell with them too.
Make sure you download the stable release if you want to try (spoiler text under the main dev download links).
