Oh wow this game has huge potential. Still there are some things that was bothering me and i think that improving them would be nice.
1. Skippable stat checks. Problem: you easily skip them (even if you may want to fail them to start the encounter or increase progesterone %) but still waste time to load an encounter. Maybe making them same as dialogue choices would be better. Even better if you could avoid encounter ON MAP just by having stat check first and THEN load encounter (i know it would work mostly for simple encounters like centaurs but still).
2. Skill descriptions are confusing. OK I know firsthand that making tooltips is torture. You do not need to actually do it.
2.1. First huge problem: base things that are true for every skill repeated in tooltips every time and take a lot of space. And sometimes what they do is still not clear.
2.2. Second problem. Info order and representation. To put it simply, every tooltip should have one order of information represented (example: costs, what it does now, lasting effects). Sometimes important BUT general data should be present Like costing 0 stamina still should be there.
2.3. Color coding is nice. Dynamic tooltips are nice (example: damage: [23] with detailed droping tip: BASE: 13 + SKILL LVL: 4 + STR:6 or even COSTS 1 [=4-END/2] STAMINA) .
I know this is not main focus of the game but, first time playing for me was like "what skill I should level up... oh no... nonononono..."
3. Dominated victory sometimes takes ages to do. Some kind of counter is needed. Never been able to do it on Mermaid.
4. "Pull hips up" skill in Prone Bone tree would be nice (that transfer position into doggy style).
Some weird things that seems to be bugs.
1. Stressful "Sliding" against the Ogre's Full Nelson STILL transfer you into UH-OH position. This creates "UH-OH" loop that drains your purity forever OR until ogre is defeated from bleeding.
2. Even if you maxed out stability PERKS and picked +3 stat bonus. Successful sex sometimes drains your stability without indicating it on Balance icon (icon shows 10/10 Perfect balance, but skills still turns yellow and red).
3. Autoequip EATS codpieces by adding them behind armor. Maybe other items as well. Needed to edit the save to actually aquire it second time to progress the Codpiece quest.
4. Anal addict check that denies you autofellatio option is sad thing to do. Lack of ability to do mutual penetration from it is also sad.
Best wishes.
