+Development Exercise - Minimal Game
+Create a ground plane. Understand rigid bodies, gravity, and colliders. Create a keyboard based player controller to move around with.
+
+### Create Walls
+
+Using Static Bodies, create walls and boundaries to form some basic world interaction.
+
+### Create Physics Based Objects
+
+Using RigidBodies, create some elements of the world that use physics interactions. You can test these against your StaticBodies.
+
+### Create AreaTrigger
+
+Create a trigger via Area2D. Create in a way that it can be used to trigger multiple effects. Turn the AreaTrigger into its own Scene for reuse.
+
+### Create Game Character
+
+Make a playable character that uses the CharacterBody2D template.
