CCG writes – “I didnt complete every level in Demonic Supremacy, but Ive played enough that my opinion would not change if I ever do beat it. People who have issues or concerns with demonic imagery will avoid this anyway even before getting into the violent content. I cannot recommend Demonic Supremacy to most despite its cheap price because the gameplay loop cannot keep a persons interest for the run time.”
