About

A pervy new professor at Beacon University sets out to teach an aged-up Ruby how to be a better Huntress. Or, as the source puts it, do some hentai stuff instead.

The trainer format keeps the loop simple: push scenarios toward corruption and humiliation, watch Ruby's resistance crack in stages, and follow the parody's own tongue-in-cheek logic rather than a straight RWBY plot. It's text-driven, unapologetically horny about it, and not interested in pretending otherwise.

We've got;
New written and place-holder content for a new Study punishment.
Stage 1 overhauling of the Gym Buttjobs, with all new DK art!
The usual SPG fixes.
This seems to have borked some of the time-flow on SOME (but not all) old saves......not sure why.....

More lessons - help Ruby with her coursework!
Plus some bug fixes.

v0.04.5.2 (bugfixed)

More artistic spankings!
Added the lovely new art from DK to the Desk Spankings scenes.

v0.04.5.1

More Blowjobs!
Still in the gym, now with slightly harsher tone.
And a bugfix for 0.04.5 which will make the gentler BJs more varied.
Also some minor spg fixes

v0.04.5

Blowjobs!
That's right, a new repeatable sex act replete with (VERY BASIC) animation and a load of NFW artworks to support it.
Currently only triggerable in the GYM and only while being nice, but we'll work on expanding that won't we.
Also some minor stat rebalancing.

v0.04.4.9.1

Spent this session on UI improvements, most of which are coming in strong.
The changes to Ruby's stat display may seem minor, but they took WAY more work than you'd think.
I essentially had to rebuild how it loads and displays the values, and I wasted HOURS trying to just get the existing model to do it for me instead.
Anyway..... here's the alpha build, now with a few more visually pleasing UI elements.

v0.02.6

Official Goofus Update
Unlocked a load of stuff hidden behind a development bug by someone who should have known better.
Me. It was me.

v0.02.5

Over here this is a non-content update.
I've fixed the problem with the music cutting itself out, a missing on-screen effect for the start of the rougher buttjobs, and a few SPG issues (and couple of non-fatal code errors).
Also rebalanced Ruby's combat growth, so she doesn't end up able to progress to the next level of combat skill after 3 sessions (because I'm a doof and set the growth scores WAY too high, now it'll take at least 9 productive sessions, more if her punishment is low).

v0.02.4

You can now hotdog Ruby!
And SO SO SO much more really, but the Hotdogging is the newest addition.

v0.02.3

Made some background changes to Ruby's starting stats and stat growth to make encountering her less enthusiastic content easier.

v0.02.2

Now with Music!
Also an SPG pass and some bughunting.

v0.02.1

This is the first version, there's a devlog here Devlog (F95zone)
READ THIS BEFORE COMMENTING ON THE ART:
Yes the Generative stuff sucks.
No it's not sticking around, it was never meant to because I think LLMs are awful for any industry in which they replace a human.
But I can't draw for shit and have no money, so I can't afford to replace it all on my own.
If you like the game, but not the generative placeholders, then please consider following the funding links for real art in the Sig.
If you have constructive feedback about ANY OTHER element of the game then well thought out constructive feedback will be rewarded with a bit of generative smut, because that's become my habit.
Ongoing update to real art created by Darkkitsu is partially funded by Patreon, and the rest by me.
Every penny not taken by the tax man goes on art, this is not a money making project.
This project would have failed without the support of the few dedicated people here who've helped me bughunt, test, pay for art, and stay motivated.
They are genuine legends.
If you want to be a genuine legend then please do, it will hasten the removal of crappy art from this game AND go directly into the pocket of a real artist (who again, is not me).
UPDATE WARNINGS
For saves prior to v0.03.9!
The code changes behind the Bedroom Scenes, and the way they lock stat progress, appears to bugger up old saves.
Sorry, but you're just going to have to seduce Ruby from scratch.
For those who play beyond the available content.
You WILL end up skipping developed content when it arrives.
