+* Notes
+- we need a collisionshape to tell the physics engine the boundaries of this plane
+- add a child node CollisionShape2D to the CharacterBody2D root node of this scene
+- in the Inspector, click on Shape to determine what type of shape we are using
+
+** create script for falling
+- hit the 'attach new or existing script' button on the upper right corner of the scene dialog
+- make sure that the script:
+  - inherits from CharacterBody2D
+  - the Template is 'Node Default'
+  - Built in Script is OFF
+
+*** script functions
+- ready() starts when node is set
+- process() is called every time a frame is called
+- NOTE: better to use physics_process because that's what the engine is going to use
