Thoughts so far...
I enjoy the overall aesthetic of the ladies. Music-wise, the combat music reminds me of Ys and Lufia II, which is quite a nice thing.
Where the writing is concerned, it isn't boring and the interplay between the protagonist and company is much appreciated. So far I haven't encountered much in the way of spelling errors, and dialogue seems natural enough.
When it comes to the trait system, I feel the threat-altering traits are kinda bad. You can't switch off the threat alterations, which makes some partners more problematic. Further, you can buy both branches of alteration - they should be mutually exclusive if they are designed to lock-in. My personal preference would be the threat traits to add instant modes to the protagonist that can be switched on/off. That would allow the player to tailor their threat level to a situation.
Aside from the that, I don't know how to view purchased traits. If there is a way to review that stuff, I haven't found it yet.
In combat, it would be nice if there is an indicator for how much mastery progress remains for a skill. That way, I can use safe lulls in combat for optimal learning.
When fighting the ladies, the status effects can cover their battle portrait. For example, Samantha having one...in her mouth. While amusing, it might be a good idea to have a dedicated status area for enemies.
When selecting allies, it would be nice for Trust and Affection to be displayed. Right now, I have to visit them to see what I do (not) have. Something like "1/4" to indicate progress to the next event would be helpful.
