Thanks for playing! I considered adding enemies with complex movement patters as seen in Galaga, however due to time constraints I stuck to the simple movement in space invaders for the game jam. I am planning on releasing a few updates after the jam to balance power-ups a bit and add some more content. I will try and experiment with more complex movement patterns and see how it fits in with the game play loop, but no promises if it ends up not working out. You can follow my account for updates on development if you are interested.
