Teenage Mutant Ninja Turtles: Fall of the Foot Clan is the Turtles' first Game Boy game and is based on the 1987 animated TV series. The Turtles must battle against Krang and Shredder, and save April O'Neil while they're at it.
The game is a platformer with a neat player death mechanic where the player takes control of a new Turtle each time they lose a life, and can regain Turtles (lives) by collecting pizza.
Alyosha speeds up the Turtles' mission by mitigating as much of the game's copious lag as possible.
This run can be seen played back on real console hardware here.
