Here are some sprites of a Player character and some trees (obstacles) both have colliders attached. 

The player is able to move and slide around the screen with some simple code.

Added in Mob (enemies) and coded them to follow the Player.

The Mobs collide with the trees and the player.

A Camera was added to follow the player which was a built in node already in Godot.

However, the Canvas background remains in place so the Player walks off the screen.

Fixed the Canvas so that is stays with the camera as it moves rather than staying in place.

Added a Gun sprite to the Player which rotates around it and follows the Mob enemies.

The Gun now has a Projectile which fires automatically, disappears after a set time and new instances of it spawn.

The Projectiles also disappear after colliding with either the trees or the Mobs.

Added a health bar to the Player and attached it to the its Health so the value of the bar goes down as the player takes damage.

The Mob enemies now spawn in from offscreen, die with a smoke animation and damage the Player.

When the Player's Health reaches zero, the game state is paused and a new Canvas with a Label displays the text "Game Over" with a semi-transparent grey background.
