There's also a great running gag about how many times you keep killing a cannon fodder enemy named Williams - nice dig at how beat 'em ups reuse enemies. When he dies he says things like, "There's more where I came from" or "I'll never die!" It all culminates in the final boss fight where the last boss runs down a list of the wrongs you've done that he'll make you pay for, including murdering countless Williams...es.
Skullmageddon has become one of those memorable characters I'm going to remember for a good long while.
