Bright Man - Screen 1

Whether first or second, the first section (nay, the whole first half) of Bright Man's stage is the same

Movement on this screen is fairly precise, and the timing of kills matters to avoid the lights going out at the wrong time.

For example, the first shot is fired after one slide. This way the second enemy (a dark enemy) can be shot before the fireworks from the first green (light) enemy stop.

Do note the last shot to kill the last enemy is important - if it misses, the enemy will likely knock Mega Man into the pit if you are moving at speed.

That said, the last jump should be off of a slide, jumping almost as soon as you land.
