+# Space Shooter
+
+## Introduction
+In this on-rails shoot-em-up demo, the player gets to control a Space ship flying through a 2D version of Space, while firing their lasers by hitting the Space bar.
+Various enemies will enter the screen from the right and try their hardest to destroy the player's ship.
+Shooting these enemies will award points and the highest score achieved is kept in a one-entry leaderboard.
+Avoiding the blocky obstacles and the enemies is key to survival and high scores, so good luck and have fun!
+
+## Controls
+* WSAD or Arrow Keys to move the ship
+* Space to fire lasers
+* Escape / ESC to stop playing and return to the main menu
+
+---
+## Godot Concepts presented in the demo
+### Editor Workflow
+* Importing assets (images, sounds)
+* Using Scenes to group Nodes into small, mostly self-contained units of functionality
+* Using a TileMap and TileSet to place obstacles in the level
+* Use of AnimationPlayer nodes to both animate properties (position, rotation) as well as trigger functions
+* Using a Parallax Background to give an impression of speed and distance traveled
+
+### Scripting
+* Using signals to communicate between Nodes that are created in different Scenes
+* Using groups to tag and identify Nodes
+* Interactions between KinematicBody2D and Area2D nodes for hit detection / collision
+* Use of VisibilityNotifier2D to remove Nodes that move off screen
+* Dynamically instancing loaded Scenes as Nodes
+
+### GUI
+* GUI Containers for organization and positioning
+* GUI Controls to start and stop gameplay
+* Use of a CanvasLayer to keep GUI always on top of the gameplay screen
+
+### Miscellaneous
+* Persisting a "savegame" in the user directory for the highscore
+
+### Interactivity
+* Player input for movement and firing
