Blades of Steel is a hockey sports video game that was developed by Konami for the arcades and was later ported to game consoles and computer systems such as the Game Boy, NES, and Commodore 64. In addition to the standard hockey gameplay mechanics, it features a fighting minigame where two hockey players can initiate a fight, with the loser being sent to the penalty box. There are also intermissions where either a generic hockey ad is shown or a minigame can be played that advertises other Konami video games.
Walgrey here plays the Game Boy version and ends input as early as possible to narrowly win a game against a pro hockey team. While that team manages to score a couple points, their AI eventually breaks at certain moments, allowing Walgrey to coast by with scoring only three points and to end input about 4 seconds earlier compared to previous run.
