A Pestilence of Maths

Concept: “A plague of madness spreads across the countryside: people hopelessly repeating strings of numbers and words until their head bursts into flames and they die in shrieking violence.”
Content: Includes an ad hoc sanity metric, random travel events and tower rooms, and a whole lot of exploding heads
Writing: Clean and characterful with dry gallows humor and well-chosen, interconnective details
Art/design: Effective and appropriate graphic choices that interact cleverly with the concept
Usability: Packs a fair amount of tension and grit into a relatively small package
