Tips & Hints

Episode 1:

If you are caught in an ice cube, you are safe from the shooting robots, until they break the ice.

The way to reach the secret city is in the sixth level. There is a spot where you jump over a small hole. Falling directly straight down the hole (otherwise you'll hit the flames) will land you in a hidden area. At the far right of this area, there is a transporter that will take you the secret city.

In the last level, you can't kill the Vorticon by SHOOTING him. What you can do, though, is get above him and shoot the chain that's holding the platform above him in place. It will fall and crush him.

Episode 3:

If you go to the island with the Grand Intellect's castle on it, wait next to the seaweed. Eventually, the Loch Mess monster comes by. Get on her back and she will take you to a secret island.

A complete translation of the Galactic Alphabet can be found in the secret level. When you first enter the level, jump up onto a ledge, keep going up, and eventually you will find a "school," with the translation written on the blackboard.

Cheat Codes

On the map, hold Left SHIFT + TAB to be able to be able to go anywhere.

Press G + O + D for a pogo stick, Extended Jump Mode, and God Mode. To use Extended Jump Mode, use the pogostick and hold down the jump key. If you use this code at the map screen, it has the same effect as the first cheat code.

Press C + T + SPACEBAR to get all key cards, 99 ray gun charges, and the pogo stick.

Press F8 for some weird screen effects.
