The card game is meant to be pretty simple. We've added the weather/seasonal buff mechanic which does incentivize players to build a deck around a certain card type over another. (Eg. Winter gives +2 on Paper).
When you say dating, you mean like taking the girls out on a date to level them up? We've thought about how much gameplay to add to it and we're open to adding a little mini-game for that kind of thing but we don't wanna make it too complex and content heavy as more characters and date locations get added, it kinda adds up.
Thank you so much for the feedback and enjoying the game otherwise!
