This game is a Bitsi game, a platform which has art with minimal palettes and simple responses to movement keys, as well as text. This specific bitsi game provides a new image for most (but not all) lines of text.
There aren't any choices as such. It's just a narrative essay about writing; what is the gap between characters and their author? How does fan fiction come into play?
The writing is good, the art was inscrutable at times but also well done. There wasn't anything wrong with the story/game, but also it lacked many of the elements I most enjoy about interactive fiction without providing a substantially exceptional experience to make up for it.
Overall, short and well done.
