Sure! Here's a simple implementation of the "Altered Worlds" RPG game, using JavaScript and HTML, suitable for smartphone operation. The game utilizes pictograms for ease of understanding. Copy the code below and save it as an HTML file to play the game:
Welcome to Altered Worlds!
The game starts by displaying the game title and an image as a start button. When clicked, it presents the player with a selection of two character pictograms (warrior and mage). After selecting a character, it shows a message and another image to begin the battle.
During the battle, the player needs to click on the fight image within the given time. Upon winning the battle, a victory message is displayed, and the player can click on an image to end the game. At any point, if the player wishes to quit, they can click on the "emozi_all/battle.png" image to directly end the game.
You can update the pictograms (start.png, warrior.png, mage.png, start-battle.png, fight.png, end.png) with your desired images to match the theme of your RPG game.
