Longest ZZT Game Ever
This 1994 world is labeled the "Longest ZZT Game Ever". You are put in a giant room filled with ammo. Once you spend the time collecting it all, you enter one of the two passages and find yourself in another empty room. And another. And another. And another. The joke is that this is technically the "longest ZZT game ever" because both of the passages lead to the board they're in, and thus the game will technically never end. There's a fade effect on the title screen (likely taken from something else), but otherwise there's nothing here beyond the cheeky joke.
Skip this one. Instead, play The Even Longer ZZT Game or its sequel The Yet Longer ZZT Game, both of which are parodies of the concept with proper game design that deliver on their titles in creative and entertaining ways.
