The Last to Fall - Progress Update 4

I am still learning how to use both collision layers and masks, as well as signals in the Godot Game Engine. So far, I've managed to detect collisions between the player and the enemies and vice-versa, so now I need to learn how to make the two nodes communicate with each other. Doing this will also help me finish the scoring system. Then all that is left is making a title screen, game over screen, and to add sounds to the game!
