Can probably remove the curTokenId field as well and replace it in the giveToken function with a call to totalSupply()?

// remove: uint256 curTokenId = 1;

// Gives an ERC721 token to an address
function giveToken(address to) public onlyOwner {
    _mint(to, totalSupply());
}

This would start the first token to have id of 0. This is what I usually see, but if you want the first token id to be 1, then you could easily adjust that.
