Sure! Here's a simple text-based game implemented as a single HTML file, utilizing JavaScript, and enclosed in script tags. The game represents a flesh maze with red doors, teeth, eyes on the flesh wall, and the objective is to find the exit which is a hole. Please note that since the game is text-based, no pictograms are used.
To play the game, copy the code above into an HTML file and open it on a smartphone or any web browser. The player will be prompted to enter their desired movement direction (up, down, left, right). They need to navigate through the flesh maze, represented by letters (E for eyes, F for flesh, D for red doors, T for teeth, and H for the exit hole), in order to find the exit. Once the player reaches the exit, a congratulatory message will be displayed.
