This is, if you haven't guessed it already, a version of the arcade game Scramble.
The program quality is overall good but overdoes it slightly on the sound side. It plays tunes at the beginning of each attempt using all three voices excellently.
The game is played using the joystick control. When you press fire bottom on the joystick you both fire the laser and drop a bomb, which with a bit of practice is very very handy.
The pricing-of this game is warranted with its quality.
There isn't much you can say about such a popular game as this, although left to its own devices, the frame will show the whole "Tunnel" to the very end. A help to see where you've got to go.
There are no instructions supplied with the game, apart from those given on screen. As usual, no-one has found a RUN/STOP disable, and this game is no exception.
A game which will keep the youngster programmers - and some older ones too - happy for hours.
