Commodore 64

Delta

Title screen

Part of the scrolling title guide

High scores

Game start

Avoid the grey debris

Shoot the central one

Again, the blue one is the 'sweet spot'

Careful here

This could be tricky

Avoid the centre of the screen

Some waves are better to avoid than trying to shoot them

The top and bottom of the screen is often restricted from level 2 onwards
