Go on a date to the aquarium with your amnesiac girlfriend, Christina Yott. Visit the sea otters, the jellyfish, the sea otters, the penguins, the sea otters, and... hey, how did we get to the aquarium?
Totally not a metaphor for dealing with anything else with limited memory.
This scenario contains a scripted Author's Note, which is hidden by default, and a custom event script to trigger Christina's amnesia. You can use the following commands in /story mode:
"/anv" to hide/show the Author's Note display, at the bottom of the screen
"/an X" to set a new Author's Note
"/and Y" for strength, where Y is numeric (1-9, default 2) and the lower the strength is, the more effect it'll have on the story
"/evv" to hide/show the event status display at the top of the screen
"/evt" to toggle the event
"/evp" to change the event period (default 30).
I recommend keeping events enabled.
