Pretty decent so far. Good animations. Game play loop is a bit too tedious, maybe increase the amount of points you get for getting an answer right?
Couple big issues:
the menu has no button to return to the game(at least on android).
It sometimes displays the incorrect amount of money.
For some questions there are no right answers or duplicate answers that give incorrect responses.
Several errors(at least on android), some cause answers to be forcefully chosen.
Designated gift items aren't giving points to the respective girl.
Overall I'd give it a 6.5/10
