 	- Check if running in a lower frame rate affects movement
 	? Write entity flags to scene file or when saving entity to file?
 	? Add scene init/de-init function hashmap that maps a function that should be called when scene is loaded and unloaded. Save this to file for every scene or map functions based on the name of the scene?

 	- Release mouse when window loses focus and limit fps
 	? When saving a scene entity entry, save the changed properties as well, that way when the scene is loaded, we load the base properties from archetype and the ones we changed per entry are saved when we saved the entity
