About Mermaid Testing
Welcome to Mermaid Testing! Have fun creating your own characters, transforming into a merperson, and mastering your magical powers! If you want to see more updates, please like the game to show your support! It means a lot to me. :) 🧜♀️ Power Controls: 💧 Water: Click on the ocean to form a water bubble, then click again to throw it. Water bubbles can transform a player into their merperson form. 🧊 Ice: Click on a water bubble to freeze it. If a frozen water bubble hits a player, it will damage them. 🔥 Steam: Click on a water bubble to boil it. Click on merpeople above water to dry them off faster. 💚 Jelly: Click on the ocean to form a jelly platform. 🌊 Dive: Run towards water and jump to dive in.
