Baba Is You: A Horror Game for Functional Programmers

Description

A tweet by Murat Kasimov (@iokasimovm, fox avatar, posted 1h ago) reading: 'Taking rest from functional programming by playing a horror game with global state, assignment statements and undefined behaviour.' Attached is a screenshot of the pixel-art puzzle game Baba Is You, showing word-block rules on a dark dungeon map: 'BABA IS YOU', 'WALL IS STOP', 'ROCK IS PUSH', and a column 'CRAB IS DEFEAT / FLAG IS WIN / JELLY IS PUSH', with sprites of Baba (white rabbit-like creature), a rock, a jellyfish, a crab, and a flag.
