NES Elevator Action Speedrun

Here is a speedrun of NES Elevator Action recorded live on Twitch on March 6, 2022. The speedrun plays the first four levels, after which the game loops and becomes basically unplayable. The strategy used prior to this recording involved an overflow of the enemy AI "aggression". Essentially, the enemy AI will increase the frequency of movement and shooting speed as time goes on, and the starting level of aggression in Level 4 is very high. However, there is a safe spot where you can stand behind a wall and the enemies cannot find you. After waiting long enough, the enemy aggression increases so high that it overflows back to the basic Level 1 aggression. The drawback is this process takes a very long time (about 14 minutes of waiting). Since this run doesn't wait in this way, it beat the world record at the time by about 12 minutes.
