This is a pretty damn wild game and definitely one of the full-out gorier submissions I've seen in the jams. I think the commitment to the guts and gore is brilliant! I do think it was great to have furnished the environment with some context and story. A cult ritual gone wrong is a spot-on horror trope, but I like how you made it your own by mingling a post-apocalyptic element to the story. The nuance of the game was great too - it was refreshing to not have an intense game that didn't have a monster per se!
Feedback-wise I think there's only a few things I can identify for constructive criticism. I think more diverse environmental storytelling could be helpful instead of the same notes everywhere. Kind of like how in Bethesda games you see skeletons strewn about and can piece the story as to what happened from their surroundings. Exploring different texts and sources of narrative can be highly rewarding.
Thanks for submitting The Cult Below to the SCREAM LITE jam!
