Absolutely love the game and the continued direction you're taking it. If you're looking for ideas for moves, how about some chest/breast attacks like a slap, bite, lick and/or suck. Maybe mix it up for variety: licking while in standing grab, slapping or even kneeing while you have them kneeling and biting/sucking while on top. Seems to be something that may mesh with your current positioning on the ground or any of the grabs, so just tossing a few ideas your way should you be interested. Another move possibility might be a forced ass smother while you have the opponent on their knees as a humiliation/domination move to drain willpower.
One thing I am uncertain about, the damage given during your slap while laying down attack. I can't tell if the damage is so little that it is almost unnoticeable, or if it is really inflicting zero damage currently. While on the topic of damage, the passive damage accumulated while being pinned seems a little high currently, but maybe that's by design.
If/when you decide to take this to Patreon, I will be happy to become a subscriber. Best of luck to you!
Oh, last thing, I'd say the vast majority of the sound effects are fantastic, especially the voices/knee attack and slaps, but the sucking/face sitting one could use a little work in my opinion. It sounds almost mechanical, rather than sloppy/wet.
Hope the project continues to go well for you.
