2D Shooter

Your proposed modifications are a little too small. Based on what you have described what I think you should do to help earn full points is create 3 new unique enemies to use in your levels: this means making each enemy behave differently from the existing by doing a mix of the following: adding weapons to them, adding lives, making them have more hp and/or varied speeds, and for each enemy make them visually distinct to represent what their new role is, you can do this by using multiple sprite renderers as objects childed under the original game object and using the color option in the sprite renderer to make more complex visualizations for the enemy. When you submit your final submission, you should describe in detail each new enemy you made and how it presents a unique challenge to the player compared to the other enemies. Even better if you can make a few levels that really show off your new enemies.
