Thank you for the feedback, I appreciate it!
I'll actually be taking a look at those 'free' moves in upcoming updates. They are currently uncategorized, but I do have some ideas on how to handle them now that you've mentioned them. Might lean more on that Lust buildup as that mechanic is currently very basic and this might add some flavor to it. Alternatively, I might group them into new categories (Such as Sera's Spectral Slash being Concentration) and the more restrains a character has, the less damage and accuracy the move has.
When it comes to bugs, I'll be looking into it when I have the time this week. I'll be releasing a small patch that hopefully fixes these bugs, along with some more that I've found myself.
And finally, I'm glad that the artwork that I have currently serves the game well, technically unfinished as it is!
