MAP21: Diablo's Heart (Kama Sutra)

MAP21: Diablo's Heart is the twenty-first map of Kama Sutra. It was designed by Adolf Vojta and uses the E2M3 music from Heretic. The version of the music used in this level plays at a slower tempo for unknown reasons.

Inspiration and development
Adolf Vojta's comments on this level :


 * The second red-cave map but slightly harder than map11 :) And also pretty different gameplay. For some time you have no weapons and you have to reach them in a pacifist-way. Then most of cells are placed at the exit so then you could finally go back and kill most of the cratures [sic] which annoyed you all the time :)
 * And I think it's my only map without SSG...

Secrets

 * 1) One of the first steps is tagged as secret. You can jump over it if you want to. (sector 73)
 * 2) The room behind the last cyberdemon is tagged as secret, you can't avoid it if you want to finish the level and kill John. (sector 135)
