Brilliant as always. Could do with a little shield option, sometimes its a little unfair with the enemy fire. Oh, and did someone say it needs game music? haha. Awesome Job, Moon Patrol was one of my Favs on the Atari 2600.
Actually, I removed a few things because I found it was *too easy* in CSpect, but on the Next its a whole other story! The aliens really didn't drop bombs as frequently as that on CSpect, but now they're fairly aggressive.
