Sirène

Sirène is a side-scrolling shooter where you control a mermaid called Nina, who has to fight her way through waves of enemy creatures on her quest to find out what has caused them to become so violent. You start the game with three hearts, which you can replenish by collecting additional hearts throughout the stage. There are four different weapons you can use to aid you on your quest: the trident, your default weapon; the bubble, which can fire rapidly; the shell, which fires in three directions at once; and the magic, which can be charged up to release a powerful blast. Throughout each stage you can also find a shield that make you temporarily invincible, and a starfish which provides you with extra points.
