JQ5 - Backup dancer rampage!

My entry for #LudumDare40
This game took 16 hours to make. 

A game about zombies who take over the world through the rhythm of pop music.
However there is a twist: the more backup dancers you get, the harder it is to navigate the levels!

Features:

• 10 playable levels
• 4 different enemies
• various environments
• DANCING

The thought process I underwent to make this game

The theme is: "The more you have, the worse it gets"
Having more player characters makes it harder to move
Q: why would all the players move together synchronously?
A: because they are dancers
Q: what is the goal of those dancers?
A: to recruit more dancers
Q: what is an easy gameplay mechanic to recruit more dancers?
A: to touch people
Q: what is a good X that converts people to X on contact?
A: ZOMBIES

Hence a game about zombie backup dancers.
