General Information
The Stars show all interactable spots however they aren't always available. Some seem to depend on if the clothing state is normal/partial/naked. Some respond only to Oral or only to Hand.
Each Girl gets a fixed second skill at level 30 (all skills except the Final Boss's are available through this, if you were wondering why the Humans and the Elder Succubus have skills that you can't even see the descriptions of)
Solicit is necessary to draw in customers early on, use it when several customers are near the entrance, reasonably early in the night. Also potentially during the Final Boss phase/
Refusal is useful early, but certain girls' skills reduce its use. You get 1 Love Point for each night that you refuse a difficult customer while a girl is working, this is useful to get Slimusu/Merly/Ibume (Shadow)/DeDe to 100 Love.
Assault is busted when used with 70+ MP (duration and power scale).
The brothel closes at 5 AM skill duration past that is wasted.
You get rewards for satisfying the individual girls in each brothel (MP cap increases, techniques to research, management cards, ability to see the girls schedules/rewards)
The shortest way to get a girl to 100 Love is an S Rank clear, followed by an A rank clear that's close to but just under 200 Satisfaction (Full Pink Satisfaction Bar mostly covered by Yellow), an A rank clear followed by an S rank clear Caps at 80 (so you'd require 3 visits).
If there's a star circle that only becomes visible when using Observe (and may have Fire Works) that's the girls weak point. They are still present even if they haven't been Observed, so you can use them.
Money is plentiful after you clear the initial block, have enough to make the monthly payment at the end of the month, but otherwise buy everything you can afford at every opportunity
Some Player skills have multiple ranks, they turn yellow when they can't be upgraded further.
Research I/II/III, Sperm Lord, I/II/III, Sage, Forced, Dual Wield and Observation are purchased skills.
Guide I / Referal I / Inspiration I are purchased skills but II/III come from use.
Other skills come through progression (through using them, reaching certain thresholds or meeting certain requirements)
Cow Race Info
Rub = Boost (Auto-Boost is okay)
There are actually 2 circles on the breasts slightly apart, try moving slightly if you aren't getting points for Rub / Suck.
The partially undressed form is buggy for some Cows, and doesn't interact properly, so avoid it until you satisfy the girl once.
Like Different Flavor = Satisfy several different (cow) girls
Kaori (A mistranslation/bug that's also a spoiler)
MiMi:
The 1st Voucher unlocks Moonlight field. Satisfy MiMi to unlock Beasts.
Estrus is the
Very few interactions work while fully clothed (Only head pats?)
The 2nd Voucher is only for a Cutscene.
Her shop selection resets after each gossip, or buying advertising, so you can shop multiple times in 1 visit. Gossip / advertising resets each week.
The Cat Contract is available in Week 4 of each month when you have a free slot (you will sometimes need to fire and rehire a girl to get the game to register a slot as open) and will work for 28 days from purchase (purchasing it while you have her resets the duration). DeDe is otherwise a standard Beast (can level, gets a 2nd skill at Level 30 etc)
Questions:
How does Wonderland Enhancement upgrade ? I don't know how I unlocked the base skill, I got the 1 star upgrade from satisfying all the Foxes. Is the 2 star upgrade available?
