Today I created a title screen.
I also changed the health points each enemy has and they change from happy to angry as they are shot.
I added background music.
Today I created the enemies, bullets and added collisions masks.
I gave the enemy hp that decreases if it is shot.
I added a cool down that decreases my shooting speed.
When the main character is shot, the game restarts.
Later today I will add a background and more mechanics to the game to make it not boring.
