Silkworm CHEAT MODE: Press the [Help] key and the fire button together and you'll receive infinite lives. You can now also move through the levels by pressing the numeric keys [1] to [0] and the minus key. If you have the latest version then attempting the above will reveal the message: "Congratulations!, you have found the cheat mode... unfortunately it has been ZZAPPED!". If this is the case then you must type 'SCRAP 28' on the options screen instead. This will have the same effects as the original.
