I have super cute game on Steam called Glowfish! In this game, one plays the role of a cute glowfish. The object of this game is to save your friend, Coralline, who has been kidnapped by the evil Dr. urchin.

Navigate through numerous underwater, ocean landscapes as you meet many charming sea creatures and fight evil echinoderms. To defeat the enemies you must save your captured friends. Then, you and your friends can blow up the enemies or you can shoot blasting bubbles at them to win the battle. You also collect treasure and powerful super chums to help you along the way. If you want to dive into a game and be dazzled, I highly recommend that you try this one! Have fun!
