Use the left and right arrows to steer the spaceship and the space bar to shoot Thanos' aliens. If you would like, you can use the up and down arrow keys as well to navigate the map.
I learned how to make a shooter game from Warfame so big thanks to you. In some instances, it is somewhat glitchy where you fire the bullet but it doesn't actually destroy the alien. Just click once to the right or left and continue shooting the alien.
