  Thank you for your cooperation

There are no endings, only divergent possibilities. I could tell you more, but then I would have to strangle you with a candy necklace... (Warning: This work contains relatively graphic violence and other darkly-comic subject matter like espresso-battles to the death and suicide) This story (or stories) is an experiment in non-linear storytelling and a "five-finger exercise" in writing fiction after a long hiatus. Thank you in advance for your cooperation... Have fun!


*Note: This story was aborted and will be likely rolled into another "collection" like my other story, "Thank you for your cooperation". As there doesn't appear to be a way to delete stories from Adventure Cow, I will keep the unfinished story online for archival purposes.

  Akabane Nights

By: D.H. Harrison (posted by Chris) (Horror, Twine)

A short story where you play as a vampire and try to survive the night in Tokyo. From the author: This is my first Twine game, an attempt to create a sandbox-style experience. You're a vampire living near Akabane Station in Northern Tokyo (not too far from where I live!) There are a few different endings, though the main goal is simply to survive the night. You could just go out then back to bed if you want! There are several ways to die if you're not careful. It's also impossible to do everything in one night, so you have to replay it to see all the different things you can do. Time passes as you move to different areas. WARNING: It has bad language, (mild) sexual content and graphic violence. You can also stalk and attack people on the street, so potential TRIGGER WARNING!

  Fly on the wall

There is a fly on the wall... But it is not really a fly... And it wants you to decide who lives and dies. (Complete, but not fully proof-read and tested as of yet)

  Next Door Taker

"Help me." (Trapped birds flapping their white wings inside a cage that's just too small) "Leave." (Dust, rot, gangrene, shackles digging into skin) You walk forward.
