Oversomnia v0.1d

Mainly fixes minor errors and bugs found by YNOnline Players. Only other significant changes are:

• Swapped two connections in the world that ultimately leads to the ending, to make it less out of the way to reach
• +1 Ice Sculpture form
• Killing the NPCs in Music Symbol World now has an impact on the BGM
• Added some visual indicators for the Deer effect in some spots around Ventilation Passage
