The Artifact


Hint:
There is a UFO in the artifact. UFOs can only shoot one direction at once. They have a preference for which character to shoot at.

Full Solution:


The UFO will fire only at one character at once - the order is, in decreasing preference, Stinky, (Loof,) Qookie and Peegue. Switch to Qookie and move the boulders along green, yellow, then red arrows to push the red button. Now move Stinky to the red "X" and use Qookie to collect three keys marked in red circles. Next, put Qookie at the yellow "X" and use Peegue to collect the final key.

To leave boulders on the yellow and brown buttons, stand on the brown button in that section of the level. As a boulder begins to roll down to that button, move off and wait until both boulders are there. Move to the left of the top boulder (using the fake walls marked in blue) and push right. Now move each of the characters up to the exit, being careful to move quickly over the bottom part of the stopped conveyer to avoid UFO fire.
