What an interesting aproach to the idea...  I totally enjoyed playing it, however, I think there should be some sounds when you encourage heroes(even if it's the same sound on both sides). You can ask community for some sounds like I did, but if you don't know how to implement sound when you press a key  here's a solution;  

1. Drag a sound in unity, that will create a gameobject with AudioSource component

2.Create a new C# script 

3.Drag AudioSource component in sound field of a script

using System.Collections; 
using System.Collections.Generic;
using UnityEngine;  
public class PlaySound : MonoBehaviour {     
public AudioSource sound;
void Update(){           
if (Input.GetKey(KeyCode.RightArrow))
    sound.Play();       
    }
}
