I have a couple of suggestions for the game moving forward:
-Movement speed. Currently, even when she's running it's slower than most games' walking speed. I'd recommend increasing it a bit.
-Enemies currently pick a single body part and only ever attack that part over and over again. I think it would be more interesting if they varied up their attacks to switch which part they target.
-Sex scenes are very slow, they could be sped up a bit.
-Flavor text in the history box on the left could be a way to make the combat more interesting. Showing things like her thoughts or reactions to what the enemy is doing as they are doing it.
-Speaking of combat, I feel like this game might actually benefit from being turn based. Currently, the best strategy to win is to just hit the attack button as fast as possible to avoid the pleasure and xp from stacking too much, but this also has the issue of not being able to see the in battle H-animations as much. Having it turn based means even players that are trying to win will still see H-animations more, and you can adjust xp/pleasure values so that corruption is concern even for those players trying to win.
