Sure, I can help you create a space game where you can make planets. Here's a sample game using JavaScript:
In this game, you'll see a canvas where planets are randomly generated with a random size. You can tap on a planet to increase its size. Once a planet reaches a certain radius, a new planet will be created. The game continues indefinitely, generating and growing planets as you interact with them.
Please note that you can further modify and enhance the game based on your preferences.
