I love the music and kind of like the graphical theme, at least during the gaming part. I don't think this is the game you were actually dreaming about. Or was it?
There has to be more to it than just clicking a picture and hiitting a few "critical hit" dots. If you want to make it more interesting, make it a little more challenging.
For example, implement a credits system, where you earn credits per click and upgrade your damage with the earned credits. Maybe buy better weapons to make more damage and armor to protect against the boss. The boss surely needs to fight as well.
Make it more or less impossible to beat a boss without upgrading your abilities, your strength and your armor. The longer a fight takes the stronger the boss gets.
In it's current form you could just as well just release a gallery app with the sex animations. To make it more fun and engaging you need some story and more than just a few moans and groans.
There could also be some introductionary animations to show off the boss before the fight begins. Maybe show if the boss is a great magician or connected to a speciffic element or maybe a great warrior goddess.
If you keep grinding you will surely be able to bring this game to a higher level, just don't give up.
