I noticed a slight graphical issue. In the current free version, some of the Marina/Samarie sprites ($love_marina_Samarie, $love_marina_Samarie_b, and $love_marina_Samarie_c) will have the wrong skintone for Samarie.
Samarie's face and body have mismatching skintones. Samarie's skintone for her face is pale, but the skintone for her body is the same as Marina's. I included a picture with some example sprites as well as the color of her body compared to the color of her face.
