I just made this for the stage idea I had. Setting the tempo for the drums was the hardest part and if the Dan's Crypt part was longer I would have more of it, but it's mostly "Plant Monster" from inFAMOUS 2. Tell me how you guys think about it.

Also, keep the fight on that middle island below the island with the bridges, you can walk in the water, and the barriers for the stage are the towers on both sides add a tower in that middle island to add some difficulty, so there isn't full screen spamming from say Radec.
So in the background you'll see the villagers of Fat Princess fighting, and running across the bridge until Zarok shows up with her soldiers, and then both red and blue team work toegether to try and take her out. Zarok occasionally attacks the stage.
