Baba Is You is Arvi 'Hempuli' Teikari's ingenious logic puzzler where the rules of each level are physical blocks you push around, and rewriting them is the entire game. WALL IS STOP blocks your path, until you break the sentence apart, or better, push words together so FLAG IS YOU and win as the goal itself. Every level is a compact theorem about its own possibility space, producing eureka moments as profound as any in the genre: becoming the wall, melting the lava, making ROCK IS ROCK recursive. Its scribbly, wobbling art style belies staggering depth across hundreds of levels plus a full level editor. Winner of the IGF Grand Prize in prototype form, Baba Is You is cited constantly among the greatest puzzle games ever designed.
