Omg thanks for the detailed and long review! I really enjoyed reading it. And the banner is 100% inspired by exactly Glass Mask!
It's intentional to have some slightly horror element. In my head, there are three different "players" in the game, the actual player, the person in the modern world before reincarnation, and the villainess. I really wanted to capture the feeling of even the person in the villainess' body getting shocked by the plot twists. I don't know if it makes sense.
Thank for listing the issues too! I'll make some changes soon and upload a new version (after I finish writing the new setting I've been planning to finish). I've heard several issues with the font so I'd probably change that too.
The bad end counter doesn't go to negative. I somewhat assume people would choose to lower love points with a RO. But I realize I didn't account for the worst possible outcome when a critical failure happens right before the last BE.
