A simple game, adapted from @QuiIIus. Use the left and right arrow keys to move the Alien Flying Machine (AFM) left and right. Use the down arrow to drop a bomb onto the Ground Defence Unit (GDU) If the GDU is hit 3 times, you will win! (The number in the bottom is the health of the GDU.) The GDU will also shoot the AFM, however. Will you survive?
This is a very basic game. I expanded an engine by @QuiIIus to create a simple game. This took me about 30 minutes. It is slightly buggy. I highly recommend trying to remix this and making it better!
