The World's Hardest Game a Flash game by Stephen Critoph known for its difficulty and catchy music. The gameplay is simple: move a square from one end of a level to the other without being touched by enemy circles. Make contact with an enemy circle and you must do the whole level all over again. In a number of levels, you are also required to collect yellow circles that are needed to complete the level.

GGG502, Dado, and raflikk choose to forgo any enemy clipping glitches in this run in favor of playing the game more normally. The main reason for this is that the version of Ruffle used here is unable to reproduce the bug that makes a popular clipping technique possible. For more details, you can read the authors' notes.
