I'm glad to hear that you're interested in creating a game! However, implementing a complete game like Minecraft 2 within the constraints you've provided (single HTML file, enclosed in script tags) is extremely complex and time-consuming. It goes beyond the scope of what can be accomplished through a simple response.
I can provide you with a basic example that demonstrates some game mechanics, but it won't be anywhere near the scale and complexity of Minecraft 2. Here's a simplified example of a game where you need to collect items:
In this example, you have a game area represented by a `div` with the id "gameArea". The items you need to collect are represented by `img` elements with the class "item". When you click on an item, it hides it and increments the score, which is displayed in an alert.
You can replace the `src` attributes of the `img` elements with appropriate pictograms or icons of your choice.
Keep in mind that this is just a simple example; creating a full-fledged game with complex mechanics, graphics, and interactivity like Minecraft 2 would require a significant amount of additional code and assets.
