hi
i have a question. do you know how yo make unlocked ending?
I'm a bit confused by the question. Are you asking about how to make the game, or are you asking for a walkthrough?
If it's the former, I used a software called Flash MX. It's not particularly user-friendly. I would recommend you Ren'py instead.
If it's the latter, the walkthrough of the game is available on my site: http://zeiva.net/otome/x_note_guide.html
