As its name suggests, the plot of Collapse hinges on the player's ability to destroy structures within a time limit; in this case, structures made of sticks. As Zen the magic mole, the player negotiates the sticks, first loosening them and then knocking them down with a magic Rotix. Unreachable sticks require Zen to switch on some of his mole magic, which allows him to fly across horizontal gaps, build bridges and discourage the two floating nasties which frequently beset our subterranean hero.

As usual with this genre, weak graphics and sound belie the quality of the gameplay. Reactions and the player's ability to think under pressure are again put to the test in what is a very enjoyable puzzler indeed.
