Add story events #97
Description
As an author, I want to be able to add story events based on rules.
A story event could be a combination of an image and some text, potentially also audio) that are combined in an overlay (cmp. SuperMarioWorld). The author could set up a story event and then define rules when this should appear. Rules could e.g. be based on:
- time left
- score achieved
- stage unlocked/opened/cleared
- number of stages completed/left
- potentially combinations of the above
