I agree with others - this is a very fun concept! I feel like there's a lot of potential for expanding on how you discover combinations. If you keep working on it, I imagine adding other types of gameplay might be fun too. Maybe you could have a similar concept of finding a combination of actions/conversations on a date that earn you the sexier scenes.

This is a nice concept, but it could definitely benefit from a bunch of polish~ Sounds, effects, colour and maybe even a little bit of animation. If you decide to continue working on it, I'd love to see where you take it~

Nice little game, the association between the combination of buttons associated with the art is a nice touch
