A plain interactive fiction engine, originally written for NaNoWriMo use. Features include conditional branching and savestates. Change the content of scene.c to your liking.

Create a branch with create(label, content, path):

label is the id of the branch, which you can use to refer to it in the path parsing.
content is just plain text, the actual bit of story printed to the user.
path decides what comes after reading this branch, and it's a bit more tricky - there's a simple parser included that'll evaluate certain expressions and can be used for interactivity:

"scene1" just tries to go to the branch with the label scene1 when Enter is pressed. (If it doesn't exist, the program quits, but your progress is still saved.)
"[scene2:Go to the forest;scene3:Go to the lake]" presents two choices with different targets.
"?scene4=0{scene5}?scene4=1{scene6}" leads you to either scene5 or scene6 depending on the flag of the branch labelled scene4.
"[?scene7=1{scene9:Run away}?scene8=1{?scene7=1{;}scene10:Fight him}]" If you're using conditionals inside [choice braces], remember that {bracketed expressions} will be expanded literally, so you may need to add semicolons in the case of simultaneously applying conditions.

By the way, there's no error checking with the syntax. Have fun.
