WOAH. Clever catch on the Ending titles having waltz references and having them each reflect the ending's story contents! O_O Lacking a formal dance background myself, I learnt something new today by reading your insightful commentary!
You pointed out things that I also appreciated but didn't think to mention (eg. the "ticket-stub" warnings page), or missed out on entirely. Your observations definitely enhanced my enjoyment of the game, so thank you so much for that! :D
