Glam rock dwarven Vikings

This game was created for a Polish game jam where we had to: 

• Create a full game on one a4 page only.
• Couldn't use dice.

So I decided to use song lyrics as the only players' way to change DJ (MG name here) decision.

The monstrous evil trio - Ice giant Grog, Werewolf lord Jacob, and master of deceive Mysticio stole magic horn from a dwarven vikings kingdom and tore it apart in three pieces. Now, King Olav and his shiny companions are coming for them.

Prepare to sing through all danger and enter RockHalla!
