Help with the code :/

using namespace std;

int main()
{
	system("color 0A");
	cout << "Waiting for the Assault Cube..." << endl;
	system("Pause");
	LPCWSTR Dupa = L"AssaultCube";
	HWND hwnd = FindWindow(0, Dupa);
	if (hwnd == 0)
	{
		cout << "The game has not been found... please open it before opening the tool next time..." << endl;
		system("Pause");
	}
	else
	{
		DWORD proces;
		GetWindowThreadProcessId(hwnd, &proces);
		HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, proces);
		cout << "Game was found...Enjoy it!" << endl;
		system("Pause");
		cout << "Type 1 for HP" << endl;
		cout << "Type : ";
		int Option;
		cin >> Option;
		if (Option > 1)
		{
			cout << "There is no option higher than 1..." << endl;
			system("Pause");
		}
		if (Option == 1)
		{
			cout << "What do you want to set your HP as?" << endl;
			cout << "Type : ";
			int HP;
			cin >> HP;
			DWORD nowa = sizeof(HP);
			if (WriteProcessMemory(hProcess, (LPVOID)0x02A7A3D8, &HP, nowa, NULL))
			{
				cout << "The HP has been written sucessfully!!" << endl;
				system("Pause");
			}
			else
			{
				cout << "There was an error writing the HP..." << endl;
				system("Pause");
			}


		}
		CloseHandle(hProcess);
	}
	main();
	return 0;
