刚玩了Demo，很期待完整版！我在itch界面看到付费的选项，请问这是解锁其他章节的费用吗？完整版已经发布了？

I know one: The title screen music is actually an instrumental version of a Chinese song: 每天愛你多一些, by Jacky Cheung - a very famous singer. You can look up the English translation if you like. 

EDIT: 

2. It is played during the emotional conversation between Artemi and Sidd during the ring fight intermission: Slow instrumental version of 富士山下 by Eason Chan.

3. 情非得已 - by Harlem Yu - played during confrontation between Cole and Artemi when hiding from mind-controlling mage.
