SPECTRUM

Use the joystick in port 2 to blast away at the ever lowering wall. When you
blast a hole large enough to fit through, push forwards to activate the
thrusters.
The levels get prgressivly harder, until nearly impossible, but I have
completed the game during bug testing.
This was my second ever game. Some of the levels flicker a bit because the
blitter is too slow to scroll all 5 planes at once.

Have fun!
