I've changed the ocean tiles for the alien planet tileset from red to yellowish green (trying to make it look like some kind of acid) because the bullets and the player's crosshair blended in with the red oceans. I originally wanted to make the oceans yellow (color of sulfuric acid which could be an alternative to water for alien life forms) but the yellow oceans would've looked too similar to the sand tiles.

I wasn't going to make anymore bosses, but since I have 8 levels, I need to have 8 bosses unless I want to have a repeated boss. I decided to make it ones of those shmup bosses where you have to destroy their shield (which has orbiting generators) in order to damage it.
No gameplay screenshots because I only got the class definitions started.
