At first glance I thought tunnel man would be a sort of load runner type game. But it's not.
Tunnel man is not as easy at it looks. It’s actually a form of puzzle game.
You must collect all the sticks of dynamite as well as the detonator on each level in order to unlock the door and exit the level. But this requires some thought because as you pick up a stick of dynamite the brick above it falls down blocking your path. So you must calculate each move wisely.
This game doesn't play. I've tried using the emulator that comes with Vista as well as a DOS emulator and the game refuses to work.
