This style is similar to the warioware game and I like it.

A tip to increase game page advertising is to put all the girls in one game.

This would make the page more visible and updated, making the gaming community more interested in the game.

About girls, my favorite is Alixia Busch however if you put a Japanese girl I would be grateful.

Thank you for your advice, but it is difficult for me to integrate all the girls in one game but I will try. 

Find actresses is quite complicated. I can see for integrate an Asian woman for the nexts versions.
