This is the first H5P ever created. It uses five libraries: Boardgame, Questionset, Multichoice, DragAndDrop and EJS (templating).
You can have a look at the finished game here. We've also attached the game as an .h5p file. By renaming the .h5p file to .zip and extracting it you can explore the structure of a complex .h5p, and experiment on it using the tutorials and guidelines provided in the developer guide. This is possible to do with any of the content types provided in our examples and downloads page.
