Trapped 4

Space maze. A reassuringly old-fashioned graphic adventure where you pilot a triangle-shaped creature (an armadillo? the spaceship from Asteroids?) through a variety of rooms packed with puzzles and traps for the unwary.

In fact, the puzzles aren't really that difficult once you work out what the various buttons and things do, but the gun turrets (and other horrors) attacking you all the time make it as much a test of your reactions as your mental abilities.

Arrow keys for directions, A for Action, M for Menu, Z to drop bomb (if available), Mouse click when text items in boxes appear on the screen.

If you get stuck on one room, go back on your route to see if there were any other exits to other rooms you might have missed. Bombs are effective against some enemies - but not all.
