A Snake clone made the year before Nokia made it go viral!

WormTech is a virus that has been created to destroy important code from your competitors machines!

Guide the Worm around the screen and collect the digits to destroy as much code as you can.  WormTech will grow with each number collected and will soon start to fill the screen, but keep going and don't hit anything except digits!


Use a joystick in Port 2 to move Worm around the screen.

Shift Lock will pause the game.

Additional Info:

This was the first entirely machine language game I made, created to help me learn how to use assembly language.

It features my first attempt at using the SID chip and my first attempt at a bitmap screen.

It was put together using a Commodore 64, Action Replay VI cartridge and Datasette.


Code, graphics and sound by Graham Axten, 1996
