Basic Game: Mermaid will collect Crystals! How to play? 1. Move your mouse pointer to move mermaid. 2. Press space-bar to end the game. Main Idea: 1. To understand the following blocks: show, hide, switch backdrop, wait until, text-to-speech. 2. To introduce 'duplicate' option with one crystal sprite, for creating many crystal sprites. Extensions: 1. Timer can be included. 2. Crystals can be moved randomly, so that it is tough for the mermaid to collect!
