Spelunky is a very rare thing: a game whose mix of core physics, judicious mechanics and random chance combine to make an experience which can sink joyous hours even if you're very bad at the game and don't care or aren't able to achieve any kind of significant achievement - ...but which is simultaneously one of the few games of such depth I have been driven to complete. It is a remarkable case study in harmonious mechanics, clever ideas finessed to ergonomic perfection, and a game world that continues to delight and reveal new possibilities for fun undertakings after years of play.
