Script

In this game, the player can navigate a 3D environment represented by 2D pictographic tiles. The player can move forward and backward, rotate left or right, and look around by changing the viewing angle. The game uses a simple raycasting technique similar to the graphics in the game Doom. The player can explore the map and interact with the environment. The game is controlled using smartphone operation, assuming touch events and onscreen controls are added to the code.
