Sure! Here's a simple text-based game where you can use your virtual $10 million to buy various items. Since you mentioned using pictograms, I'll represent the items with emojis. This game can be easily embedded in a single HTML file and includes JavaScript code enclosed in script tags.
In this game, you start with $10 million (`money` variable) and an empty inventory. The `buyItem` function allows you to purchase items by deducting the cost from your money and adding the item to your inventory. The `displayInventory` function shows your current inventory and the remaining money.
You can customize the items and their costs to fit your game's requirements. Keep in mind that this is a simple example of a game implementation, and you can expand on it to add more features, interactions, and visual elements as desired.
