- Architecture needs rethinking. Too many abstraction boundaries between classes and their parents.
Thoughts on entities in the game: 
	The current core of an entity is which mode it is in
	Modes decide behaviour, how it draws, how it affects others
	Modes, imo, should be how we communicate between the behaviour and presentation layers
	The drawing layer decides how to present the current state of any object
	The logic layer decides how an object behaves given its state

	Extract text, presentation in to resources
