This stage is pretty slow, but it's a fun one. The hacker has developed the elevator sequence into an enemy gauntlet. Without the ability to shoot up, you're forced to dodge all kinds of attacks. He also turned the simple moving spike segment into something where you have to keep up with descending platforms to stay alive. You also need to be pretty quick to grab that letter.
Gyro Man isn't that hard, but sometimes his 3 blade attack offers a pattern that might trip you up. The rest is easily learned and telegraphed. Gyro Man has another attack he doesn't show off in this fight, where he ascends a short distance and does a parabolic dive across the screen.
