1. It was added in a time where I was in the Rong Rong Discord server. Like you said, it is not needed, so it will be removed.
2. There's a secret 6th ending, only available if you bought the digital artbook.
3. Will add it later.

Do you have any explanation for the weird camera shaking at around 2:20?
