Good job on finishing the game! I would like to see more different enemy type, or maybe even powerup for your own fire "ball". The idea of one life is can be executed better in my opinion, the player need to be given more tools to defend themselves if there is only one life. The enemy does not give a clear indication when they are firing a shot and this can cause some frustration for the player. Once again, goob job! Would love to see how you improve after this.
