For the player character's running animation, it's really stiff because of how completely still her upper body is. Looks like an old Hanna-Barbera cartoon like when Shaggy and Scooby are about to run away from a monster.
Same for the attacking animation. Her body doesn't move at all as she swings the sword, which makes it feel more like a puppet. She should at least step forward slightly and bring her weight down with the sword, that'd help impart some power to it.
Movement feels decent, though I think it would be good if the jumps were slightly higher. It'd also help things feel more responsive if her jump height varied depending on how long you pressed the key. A slight tap would only go a little bit off a ground, where as if you hold it down she'd jump to her full height.
For the H-scenes, it'd help for the game to either zoom in during scenes, or for there to be a button so players could choose to zoom in themselves. Adult content isn't much good if you need a magnifying glass to appreciate it.
Recognize that it's very early, but I do look forward to further developments
