Deployed a pingpong Game on XinFin XDC Network.

Deployed a PingPong game on XinFin XDC Network. Working with games is more interesting then playing that game :P

Check the code here:
pragma solidity >=0.4.25 <0.6.0;
contract Starter
{
enum StateType { GameProvisioned, Pingponging, GameFinished}
StateType public State;
string public PingPongGameName;
address public GameStarter;
Player public GamePlayer;
int public PingPongTimes;
constructor (string memory gameName) public{
PingPongGameName = gameName;
GameStarter = msg.sender;
GamePlayer = new Player(PingPongGameName);
State = StateType.GameProvisioned;
}
function StartPingPong(int pingPongTimes) public
{
PingPongTimes = pingPongTimes;
State = StateType.Pingponging;
GamePlayer.Ping(pingPongTimes);
}
function Pong(int currentPingPongTimes) public
{
int remainingPingPongTimes = currentPingPongTimes - 1;
if(remainingPingPongTimes > 0)
{
State = StateType.Pingponging;
GamePlayer.Ping(remainingPingPongTimes);
}
else
{
State = StateType.GameFinished;
GamePlayer.FinishGame();
}
}
function FinishGame() public
{
State = StateType.GameFinished;
}
}
contract Player
{
enum StateType {PingpongPlayerCreated, PingPonging, GameFinished}
StateType public State;
address public GameStarter;

constructor (string memory pingPongGameName) public {

}
function Ping(int currentPingPongTimes) public
{
int remainingPingPongTimes = currentPingPongTimes - 1;
Starter starter = Starter(msg.sender);
if(remainingPingPongTimes > 0)
{
