Play the game on Medium or Low quality, since the game tends to get choppy on later levels making it a lot harder to move around.

The easiest way to control Magax is to go forward for a second and then turn around for about a half-second to keep your speed down. Don't hold down the arrow key though, or it'll take you longer to slow up. It takes a little practice, but you'll get used to it.

Always attack the Chia ghosts first, they spit slime globs that are tough to avoid. Save the JubJub ghosts for last, they split up into 3 smaller ghosts which are hard to hit and harder to dodge.

Don't shoot a ghost if it's near a health orb, your shots destroy the orbs too.

Hubrid Nox will do one of three things when he shows up: set you on fire (lose a little health), freeze you (Can only go in a straight line for a few seconds), or make all the ghosts on the lever larger. Hubrid uses the freeze attack a lot, so try to get to an empty part of the level when he shows up.

Don't bother trying to shoot Hubrid, you can't hit him.

There's a bug in the game that might show up after level 8: sometimes a blip will get "stuck" on your radar, and you won't be able to go any farther even after you've gotten rid of all the ghosts. This is fairly rare, but if it does happen the only thing you can do is either let Hubrid kill you with his fire attacks, or close the window and start over.

This isn't a terribly difficult game once you get the hang of the controls. If you have the patience to play it for a while, it's worth an easy 3000 NP a day. :)
