Daniel Rammelt, also known as Super Slimer, is a level designer. He created the Qmaper editor, one of the first level editors for Quake, and used version 0.19 to create Crypt'o'Death. Qmaper was extremely buggy, often causing Rammelt to stop working on his level to fix some bug in the editor. After releasing his map, he continued to work on the Qmaper editor, improving various features. He released another map, SHAKE2!, with version 0.33.
