I started with a 32 by 32 grid and drew an upside down T shape, and coloured it in grey I added some detail in the colours grey, blue, red and green.
using game maker I removed the white background and created a sprite for when the player shoots and all the colours light up.
Update:
i replaced the sprite with one of a man holding a gun because the nature of the game has changed from space invaders to a zombie survival game.
this video highlights how the player works in the game and how the two sprites are implemented
Enemies:
the enemies in the game are zombies that walk towards the player until they are shot or they get to the other end of the screen this video shows off the shooting mechanics, the walking animation as well as the death animation
