When her hand passes over her limp "Stamen" in her talking animation. The shine texture from it passes over her hand.
Also unrelated, if you don't mind me asking, what program do you use to animate? (Guessing it's also in the custom engine the game was made in) But the stylized 2d animation mixed with some of the realistic physics with the softer materials feels like black magic. Beautiful game, music and character designs all around. Hyped to see how much quality art this game has when it's finalized.
