KUBO 2: L'Aventurier Courageux (KUBO 2: The Brave Adventurer in English) is the sequel to homebrew NES game KUBO and was developed by the same father and son duo as the first one. This time, however, the son now has a hand in the level design in addition to the graphics. The story involves a cowboy turtle going into ancient pyramids and ruins in order to find a special gem that can save a nearby village from an unspecified calamity.
LoganTheTASer, Samsara and ViGadeomes complete the game as fast as possible, going out of bounds at one point to save time, also saving 46 frames in the process.
