Hey empe3, I have some ideas that you could put in the game, I think many may like it or not...
My idea is the following: an option could be implemented in the game where we only control Sana and we can choose which path she follows (this option can be added after defeating the final boss or even at the beginning where the player will have the choice)
Along with this option, the possibility of her getting pregnant could also be included, playing with Sana, there could be a new counter in her status, a counter for pregnancy and births that she would have, but knowing that in the game, every time she gets pregnant, the rebumina game could be placing an ability that creates a false memory in Anno's mind where he will not know that she is pregnant and can proceed with my idea, also having another ability seller where the player can change the chance of pregnancy from 0% to 100%, Just one more idea and what I think would be really cool to have in the game.
Thanks for reading my idea, Keep improving your game, you do great!
