Spelunky

Derek Yu, Andy Hull, and Mossmouth's peerless, uncompromisingly brilliant, and historically transformative 2D procedural platforming roguelike masterpiece across Xbox 360, PC, PlayStation, and Nintendo Switch (the commercial HD remake of the 2008 freeware original), released in July 2012 by Mossmouth as the flagship title of Xbox Live Arcade's Summer of Arcade, winning Excellence in Design at the IGF and Game of the Year from PC Gamer while holding an 88% GameRankings and 87/100 on Metacritic and selling millions of copies, standing as the supreme, foundational granddaddy of the modern "Spelunkylike / Platformer Roguelike" genre, dropping the fedora-wearing Guy Spelunky into an ancient, ever-shifting underground cave system, armed with four bombs, four ropes, and a whip, single-handedly inventing the legendary "Algorithmic Room Template Generation" system (ensuring every procedurally generated level has a mathematically guaranteed walkable path to the exit), lethal emergent physics interactions (arrow traps, shopkeepers, damsel sacrifices, tiki traps), the secret labyrinthine quest to reach the subterranean underworld of Hell to slay King Yama, and Eirik Suhrke's infectious, award-winning chiptune, ragtime, and big-band acoustic jazz soundtrack.
