This week said lighting on the calendar
	I think we should stand on things instead

Last time:
	Objects block our movement
	We can test if a point is inside an object
	So we can stop moving down, right?

First:  Are we standing on anything?
	If so, let's not fall!
	If a point below us is inside something...

Second:  Can we jump?
	Let's make an extra rabbity jump so we can test landing on things
	Some games let you control your fall
		Why does this make sense?
		We'll do that
	Can you jump while you're falling?

Third:  Are we about to land?
	Would we be inside something if we fell any further?
		Simple enough question
		Do we need to make sure we don't accidentally fall through something thin?
		
Fourth:  Normally we can step onto stuff
	How high?
	Must adjust height to match what we're standing on
	But...do we go over or under things?

Fifth:  How about crumbly brick?
	We'll have to notify the object if the player is on it or landed on it
	A trampoline would be similar

Lab this week:
	Make a jump sequence
	if(player_pos) is in the win spot, do something
	Put in some kind of reset mechanism
