Sure! Here's an example of a simple Disney park game implemented as a single HTML file with JavaScript:
Disney Park Game
Tap the castle to check out your characters!
Your Characters
In this game, the player can unlock and upgrade Disney characters by using gems. Each character has a specific cost in gems. The player can tap on the castle to check out their characters, and they can also upgrade their characters. The character list is displayed using pictogram-like elements to represent each character.
Note that the game logic for unlocking characters, spending gems or coins, and character upgrades is not implemented in this example. You would need to fill in the missing logic according to your game requirements.
Feel free to customize and expand upon this example to create your desired Disney park game!
