Hi there. I've been playing your game every now and then for several days and would like to give my feedback.
First of all, I like how you include realistic, cartoon and anime opponents. Including stuff like bimbofication, corruption and breast expansion was also a good idea. The variety is great all around.
Now, obviously I don't expect you to do everything I ask, or do it very quickly, but here are some ideas you may consider for the future:
1- You should make explicit images for all your characters. The succubus in particular, it should be a given that she should strip naked.
2- I noticed some characters have unique phrases, but I think they should be more explicit. This is a strip game, after all. It would be nice if they said sexier stuff whether they won, lost, or stripped.
3- You could also make it feel more like an actual strip game by having the characters react more explicitly to the player losing. They could talk like the player is stripping in front of them when he loses a hand and act as if they're seeing the player naked when he loses all his money or gets checkmated in chess. Perhaps you could even give them a unique picture of them acting like they're seeing the player naked.
