Boss - Burst Man

Burst Man can be deceptively difficult. The player needs to avoid bombs scattered across the floor as well as the bubbles in the air. A missed Freeze Cracker can also knock Burst "back" away from the wall, putting him in a worse position for Mega Man.

Freeze Cracker Strat

Get into the tile next to Burst Man as fast as you can (it doesn't need to be exact, just as long as you are "close"), then FULL jump, shoot a Freeze Cracker, and move away from Burst.(Full Jump here meaning hold the jump button and do not let go until you land and jump again. Do not short it - this jump is for timing).

As soon as you land, full jump back next to Burst Man, and repeat with another close range Freeze Cracker.

Do this 7 times while avoiding the bombs (Burst dies on the 7th hit)

Backup

Jump to gain height over the first shot when the bombs explode (avoiding damage). Fire the ice at Burst on a diagonal, repeat. Just be sure to connect with the main shot and not the scatter off the wall - The rebound will knock Burst Man into the middle of the room. You can continue this assualt from there, but it will be awkward.
