Galactic Overload

You are flying through space, minding your own business, when you are suddenly attacked on all sides by violent aliens. You must dispatch them in order to escape. How long can you survive?

None of the sounds and graphics in the same were created by myself, with the exception of the health bar and the recoloring of another sprite. My graphical assets were taken from OpenGameArt and here is a list of the original creators:
