Author's blurb From the right hand side of the screen come the high speed Nibblers flying at different levels randomly generated. Some attack the dam at its highest point. Others are low-flying and move in to take chunks out of the town on the way. User summary Nibblers was written by Paul Jay and published as type-in source code in Computer & Video Games Issue 1, November 1981. It was intended to run on "a 32 column PET in 8K".
