I see where this thread is going, so here is some tips for everyone so you can improve your Gorf gameplay:
Astro Battles:
Stay in front of the invaders if possible. If you can't clear them like I do in my video that's ok. When passing underneath them to move to the other side don't fire. The shield disappears every time you fire. Hitting one or two when crossing over isn't worth it.
Laser Attack:
You must try to hit one of the ships that shoot a laser first. Whichever formation does NOT send a diving alien at you after the first laser blast, go for that ship first. Most of the time this is the right ship. If you miss, try not to keep your ship in between the 2 laser shooters. Move all the way to the right and stay LOW. Staying high up and to the right you will get trapped. Once one of the laser shooters is gone, you can stay on that side and clear the other aliens easily. The other laser shooter will stay on his side of the screen unless he is the LAST alien on the board, then he will move anywhere on the board except the extreme left, you're safe there.
Galaxians:
I start shooting a few on the right of the formation, then just before the first wave dives I move to the extreme left, drawing them all to the left. Then you can easily shoot a few as they dive and then move back to the right. I then lure them again to the left and then move back to the right. Of course this doesn't always work when more and more are diving; so remember you can stay low and avoid shots. The blue ones are the only aliens that shoot that "extra" shot when they are near your ship. All other aliens shoot right away when they dive, so if you are high up on the screen you can move downward and pick them off because they won't fire all the way down to the bottom. Biggest mistakes are staying high and in the corner. Stay in the center and draw them to the left and move down and to the corners in an emergency.
Space Warp:
Stay in the middle, but not necessarily all the way up unless you're a good shot. Stay back a little bit and concentrate on hitting the aliens when they come out of the hole. If you miss, concentrate on avoiding their fireballs, moving left and right and never in one direction more than 2 fireballs in a row or you will get trapped in the corner. If you miss the aliens, the ones that come out more in a circular pattern you can avoid being kamakazied by moving low on the screen. The ones that have the more elongated eliptical pattern stay in the middle and more towards the hole and they won't hit you.
Flag Ship:
Clear the shield from the middle to the left of the screen and forget about the right side(I was reckless on my video). Concentrate on picking off at least one of the diving aliens first; but remember they like to follow the path of the flagship's fireballs so be patient. Get both of them if you feel confident. Don't fire too much at the flagship, it only creates shrapnel that will for sure hit you. Just take one or maybe two shots per pass. Stay away from the right corner, and as the flagship goes from right to left take your shot. If you miss, concentrate on moving your ship thru a break in the fireballs back to the right. DON'T go all the way to the left corner. You can survive here better than the right, but it is a trap in the end. The flagship will only come down so far before it heads back up to the top again....
Edit: Also, take your shots at the flagship in the middle 1/3 of the screen; too far out towards either edge means shrapnel death if you miss....
