I was playing this game, and I was never able to get past the part about putting on the helmet and trying to kill all of the gods part.
as stated in your walkthrough:
Fight the conditioning process: A reconditioning helmet goes down on your head. You have to fight to prevent being brainwashed.
The object of this arcade puzzle is to destroy all the guards below and all the gods at the end of the screen. There are 4 chances-airships to get through the puzzle. If all airships are destroyed, you have to start over.
Collect all the crystals that are used as power of your airship.
You can move the airship using the mouse. Left click to shoot and right click to drop bombs.
The best hints given to me by Jenny100 are to use bombs on the guards and laser fire on the gods. Use rapid, continuous fire on the gods while protecting your airship from the fireballs-arrows. Some of your shots will eventually take out the gods.
When successful, the chair enters another chamber.
Any chance that you might have a savegame that gets me through this "battle" and to the next step? Thanks.
