Clever game mechanic, it would have been fun to see it implemented across several bra types like you originally planned! A front view and a back view may work better to show what's happening, I didn't fully grasp the situation until I read the description. The fingers can benefit from a slightly expanded range of motion, it didn't really feel like I could do much with them at first.
It's cool that you ran real photos though a filter for the images, the effect works well for a funny game like this one. Suspenseful music and reaction noises all fit the theme nicely, though the game audio should probably fade out when the victory music starts playing. Happy to hear that the two of you got to bond over coding this game, that's a very sweet reason to make it!
