It has been suggested that this jam is too OP in terms of creative freedom.
I respectfully disagree.
The point of this jam is not to force an idea by telling you what you can/cannot or must/mustn't do, but to act more like a writing prompt -- to allow you to create something on a theme that you may not otherwise have pursued, using whatever tools you have available, and providing you with a deadline to come up with a prototype.
What do you think? Should there be some specific requirements for entries? I am open to suggestions.
