Literal Spiral

Literal Spiral is a single-level joke WAD compatible with vanilla Doom II. It was designed and released in October 2019 by Worm318, as a parody of a topic on the Doomworld forums. In that topic, the original poster regarded the design of the levels of Doom II created by Sandy Petersen and SIGIL (by John Romero), amongst others, as spiraling and confusing, in their words.

Bugs

 * This map consists of a single sector, and it had its REJECT lump built by ZenNode. As a result of these peculiar circumstances, all zombiemen are totally blind and, hence, inoffensive.
 * The exit switch uses the exit linedef type 51, secret exit. Therefore, completing this map will simply restart it whilst keeping the inventory.
