Как насчет использования JSON.stringify перед сохранением данных и JSON.parse после их возврата из хранилища. Это "сохраняет" типы. Не нужно индивидуально заботиться о правильной процедуре приведения типов данных. Я также предлагаю использовать ровно один объект хранения для всех данных игры / игрока.
Ключ хранения для установки / получения ровно одного объекта данных может представлять собой комбинацию имени игры и личности игрока. имя пользователя / идентификатор ... как ...
localStorage.setItem('adventure-x-charlie', JSON.stringify(data));
... с data, выглядящим примерно так ...
const data = { moneyAdd: 1, money: 1000, crystals: 0, wood: 0, metal: 0, sword: 0, rsword: 0, hasAnvil: false };
Реорганизованный пример кода OP может оказаться что только что было сказано (к сожалению, localStorage не работает для «изолированных ящиков с кодом», но ...). Вставка следующего кода в консоль инструментов разработчика тоже делает свое дело ...
const RolePlay = (function () {
// local module functionality
// ... dealing with session data
const defaultSessionData = {
// profitValue: 1
moneyAdd: 1,
money: 1000,
crystal: 0,

rsword: 0,
hasAnvil: false
