Sure! Below is a playable sample game implemented as a single HTML file using JavaScript. It is a guessing game where the player needs to guess the names of popular animals represented by pictograms. The game consists of multiple levels, each with its own mission to complete. Here's the code:
To play the game, copy and paste the entire code into a new HTML file and open it in a web browser. Each level presents a pictogram representing an animal, and the player needs to guess the name of the animal by entering the answer in a prompt dialog. If the answer is correct, the player earns one point, otherwise, they lose a life. The game ends either when the player completes all levels or runs out of lives.
Feel free to customize and expand the game by adding more levels, missions, and pictograms.
