Thank you for playing!!!
Originally, it was supposed to be a one-shot. When you reach her happy ending, she lives there peacefully and if you try to play the game again, it'll only show her room with the sounds of birds chirping.
And while it made me happy, it didn't really work well gameplay-wise.
So I opted to have a warning when you restart the game in order to make you realise that you'll be putting her through a loop.
I'm glad to hear that you want her to be happy TT She is. (On my computer, she's living her best life as a very happy and pampered lady.)
