Thank you playing so many times!
Sorry about the difficulty, only six out of the seventeen ending are "good." With how unclear some of the effects of your choices are, and without knowing what the endings are, it can be hard to earn a "good" ending.
A save button is a very good idea. I decided against it in the face of the deadline. Thinking back, to have people play through multiple times, it would've been an encouraging addition. One I probably shouldn't have cut, and will probably add when updating.
Thanks for the feedback.
