Sure! Below is a sample game implemented as a single HTML file, containing JavaScript code enclosed in script tags. The game allows players to hatch and evolve pets, trade them, age them up, and name them. Since it is difficult to include pictograms in a text-based response, I have created a text-based game instead:
To play the game, you can copy the above code into a new HTML file and open it in your web browser. The game will prompt you with a menu and you can choose the options by entering the corresponding numbers. The game operations include hatching eggs (which grants a random pet), aging up pets (to make them neon), evolving pets (to make them mega neon), trading pets (requires at least 2 pets), and naming pets (by entering the pet index and a name). Enjoy playing!
