Use Arrow Keys to move and Z to shoot. Some aliens are indestructible. New enemies are introduced throughout the game including the Bomber Butterfly, Blaster Beetle, Bomber Beetle, and Targeting Butterfly. There is also a Boss Butterfly at the end.
This is based on the video game, Galaga as well as other related games. Most Sprites are from scratch with a few being from images from outside sources. I also used Remove. bg for these images.
