I have a personal suggestion for the creator:
The Lamia´s stuff the character in their coochie to transform them into a Lamia!
I like that!
However, Art/Sprite-vise and realistically when the Character is already a Lamia, stuffing them with the entire Snake tail in there would be very difficult!
Thus comes my suggestion: Why not make it so that if the Character has a Snake tail instead of stuffing her in her coochie the Lamia´s will now coil around them like a long Snakey hug! (if you know what I mean)
I think that should make the artist´s Job easier and simultaneously this would make the Game more ingenious! ; P
I added some pics as examples:
