Mountain King is a platforming game that was developed for multiple game consoles and computer systems, including the Atari 2600, ColecoVision, and Commodore 64. You play as a spelunking explorer, and your main objective to find the Golden Crown in the depths of an ancient mine and bring it to the top of the mountain. Bats and a giant spider lurk in these depths, so don't die or the game is over.
In this run, Bloopiero and Walgrey play the Atari 2600 version and clip right through the floor and into the temple that contains the crown without having to collect the required to 1000 points to get inside and become the Mountain King in record time.
Warning: The end screen contains rapidly flashing lights that may not be suitable for those with photosensitivity issues.
