	"""
	This is the game's main loop and it does the following:
	- runs every function in g.pending_actions list and remove it from the list if it returns anything.
	- blit the background of menu and main frame
	- run the on_loop function and blit the image or animation of every item in g.scene.menu
	- run the on_loop function and blit the image or animation of every item in main (main is hardcoded)
	- run functions on the following events:
		- chars begin entrance
		- chars entering
		- chars on center
		- chars begin leaving
		- chars leaving
	- blit messages on their positions
	- blit it all on the screen
	- blit the balloons on the screen

	Please, update the description on every change
