You will find the new changes in the Quickstar repo, for background animation: https://gitlab.com/lunafromthemoon/RenJSQuickstart

You can now load a background as a spritesheet, in the setup file as:

backgrounds:
  # key: filepath frame_width frame_height framerate
  forest: assets/backgrounds/forest-spritesheet-800x600.png 800 600 5

The information you need to add is the frame width and height, and the framerate. You can see an example in the quickstart, by changing the background that is loaded in the story file from "room" to "forest".
