Just some starting comments:

The game is like a Mr. Game and Watch episode.
You are fixed into several positions on the screen, and cycle through them with directional arrows.
There are 4 positions for the character on the middle platform when fighting the big head.
The game controls which direction you attack in, and attacks only travel one position away.
Once the head is on the ground, you can leap over it just by walking over it.
The levels get progressively harder by making the heads attack faster, and the quick time event gives shorter intervals before failing you. I repeated Level 7 about twenty times before getting it.
For Work and Consume, you can not fail a single arrow selection before Level 4.
For Nobody Wants That, you can fail as many QTE's as you want, preferably after Level 4.

begin loop:
#begin loop:
##begin loop:

##Stand under a head.
##Wait for it to attack then dodge.
##Hit the head by pressing X.
##Climb the ladder on the side of the screen nearest the head.
##Shoot the mass with an arrow.

#Repeat for remaining head.

##begin loop:

##For the big head, wait for the attack and dodge.
%%NOTE: The big head's attacks cover 2 of the character positions simultaneously. It can attack the two spaces on either side or the center two spaces.
##Hit it by pressing X.
#Repeat until you have struck the head three times.

#A quick time event (QTE) now begins. Press X to start the event up.
#Follow the arrow keys on the screen until the head is dead. Now you can take a break.
#Press enter to start the next round.

Repeat until medals are achieved.

For Time Attack (B) you just have to perform this without taking damage. The heads attack at Level 5 speed or so in Time Attack.
