Mighty Bomb Jack is a game where Jack goes to rescue his family from a pyramid. Along the way, he meets many enemies who start as mummies and change forms when they hit the ground. He also finds bomb-filled rooms at the end of each round, which work like warp rooms with a twist: you can warp ahead to the bomb room of the next round if the first lit bomb is the last bomb collected. Using this, the author warps past many rounds.
However, this movie aims for the best ending, which is obtained by freeing all the family members. This means that the authors avoid warping past some rounds in order to collect items. This particular TAS by ktwo and SpaceColonizer was done on the North American release of the game, which notably has different room solutions and different item locations, and generally has less obscure room solutions.
