Abadox/Stage 6

This stage is tube-like vertical level. You must be very precise in your movements here to stay alive. Move quickly and smash the ghosts and other menaces out of your way as soon as possible. Next, you'll find yourself in a passage with yellow lasers which activate time from time. Be very careful not to get in the cross fire when they activate. Try to move to the side when evading energy balls and move quickly to pass the lasers. A press object is up next. After you've fled through it, you meet a mini-boss.

Five nasty eyeballs. They shoot homing "seeds" at you. Run away from the seeds or destroy them. When there are no seeds around, fly close to the eyeballs and destroy them. The last part of the stage contains cannons on all sides that fire energy balls at you which will form a bird-like cannonball that charges at you. Be sure to evade. Another set of yellow lasers follows. Next up is...

FINAL BOSS: Parasitis Core
This guy is easy. Target the green spheres at the sides, and don't forget about the head. Staying close to him will save you from some of his attacks. What will also help is having a large arsenal of weapons you should have gathered by now. Don't back down, this is the last fight in the game.

Watch a little scene. There's also the last, 7th stage of the game, although it's not really a stage. You'll have to fly through the level at a pretty high speed. Avoid the obstacles until you reach the black space. Watch last scene of the game and the staff credits. Congrats! You beat Abadox!!!
