Contra Returns - How to get to Floor 127 tutorial

The actual good runs start at 2:30 (4th attempt out of 6).

A few tips:

Floor 97: Just remember to stand on the left side of the platform so you can jump to the left and loop back to the right to land on the platform on Floor 97. Don't hit your head on it.

Floors 98-100: You want to jump off the boost platform but to the right so you can move left after clearing the platform in the center column. Don't bonk your head on this platform as well.

Floors 100-101: Same situation, but jump left off the boost platform then move right after clearing the moving platform in the center.

Floors 110+: Have perfect movements and memorize! (Good luck!)
