Hello, please note that the game is still under development and you will not be able to fully complete the routes right now.
1 - Yes, the scenes are animated in l2 (and all new ones will also be animated)
2 - No, you can not. Not all girls support polygamy.
It is better to purchase the game on release and enjoy it fully towards the end of its development, if you do not have a place to store the game and update it.
Thanks!
