Changed music to something hopefully less terrible. Still isn't suitable, but I'm not certain what is. Also added some bare-bones code for a spinning sword ability on the ninja that times itself and spins by rotating every time it updates in the Game1.Update method. Not sure quite how to implement it, but if we have it rotating the same way that the move methods rotate, we should be able to rotate on 2pi and have it complete a rotation at the same rate as a player moves through a tile.
