Thank you for playing through so many times.
I'm glad the character personalities came through.
I do regret giving up on save functionality. I will (hopefully) figure out how to do that.
As for the story, the original idea was a lot darker. It is based on certain anime tropes. I did try to make it more grounded at the beginning.
There is a way to resolve things peacefully, but there isn't much in the game to direct players. I'm not surprised you ended up in the default ending multiple times.
I'm planning on adding some features to help the player understand the consequences of their choices and get more endings.
