Outside of maybe making the hips a little wider, I personally have no issue with the model at all. Probably won't change a thing once customization comes around
I'm not a huge fan of the struggle mini game at the moment, but I'll probably just give up most times anyway unless there's a gameplay penalty for it.
A thought I had that would be cool is if there were a visual way to show the struggle with the characters changing. Like, the more the enemy is winning then the more aggressively they're holding, groping, etc. With the current system, it could just be at different percentages of the enemies meter, like 25% increments. It could be done with the character as well to show she's got the upper hand, though this might be tough with the current competing percentages.
I noticed that the enemy's bar was determined by the amount of clothing there was, but I didn't know how this translated to when you lose the struggle. Even at close to 100%, I wasn't sure whether I'd lose with one failure or more. And I wasn't sure how things translated to the character's percentage. I'm guessing it's based on the amount of correct numbers you clicked, but it's hard to tell. On top of that, her percentage didn't seem to update at the end of every round.
Rather than the percentages, maybe it could just be tick markers that indicate how many times you have to succeed a full set of numbers and either the amount of ticks or number you have to press is determined by how much clothing you have. It could be a simple majority of successes to win.
Like:
100% clothing remaining
00000 (5 ticks to succeed with 2 completed successfully; FAILURE)
-and/or-
Only needing to get 5 numbers in the sequence to succeed a struggle
<25% clothing remaining
000 (3 ticks to succeed with 2 completed; SUCCESS)
-and/or-
Needing to get 10 numbers in the sequence to succeed a round.
The difficulty of the struggle could be affected by both clothing and the game difficulty as well. Maybe clothing determines ticks and difficulty determines numbers per sequence (Easy keeps the numbers at 5 in the sequence, normal has 8, hard has 10)
And as for the animations so far, rather than have a button on screen that you have to click with your mouse, it would be nice to have a keybind to progress the animation. Since 'x' already brings up the masturbation animation, maybe you could use that to also forward whatever sex animation there is. (i.e. masturbation, tentacles, etc.)
I know there's a lot there and these would add a lot more work, but I just thought I'd share.
