Spelunky

Spelunky is a roguelike platformer video game designed by Derek Yu. The original Spelunky was released as freeware for PC in 2008 and later expanded into Spelunky HD, a remastered version released in 2012 by Mossmouth with BlitWorks, featuring updated graphics, new content, and improved level design.

Gameplay centers on exploring randomized cave systems, collecting treasure, and reaching the exit of each area while avoiding traps and hostile creatures. Each run is procedurally generated, so no two playthroughs are the same, and death is permanent, making mastery a central focus. Players employ tools such as ropes and bombs to navigate terrain and access hidden areas, and they encounter a broad array of items and hazards as they descend through deeper layers toward the final stages.

Spelunky has been released on multiple platforms beyond its PC roots, including console and digital storefronts. The game received widespread critical acclaim for its design, depth, and replayability, and it has influenced a generation of indie roguelikes and platformers. It also helped popularize speedrunning and emergent gameplay in procedurally generated titles.

Spelunky 2, released in 2020 by Mossmouth and BlitWorks, builds on the original with new characters, items, environments, and features, including expanded multiplayer options. It was released for Windows and PlayStation 4, with later ports to additional platforms.
