Sure! Here's a simple text-based game that incorporates elements from No Man's Sky, including spaceships and wildlife. As requested, it will be implemented as a single HTML file, enclosed in script tags, and written in JavaScript. However, since it's a text-based game, there might not be pictograms involved.
In this simple game, you start with a spaceship and arrive at a randomly chosen planet from a predefined list. You have a 30% chance to discover friendly alien wildlife on the planet. If you find wildlife, you win the game and can continue your adventure. If you don't find any wildlife, you're prompted to explore another planet. The game continues indefinitely with each new planet visited.
