Cool idea and great music. I really like the mechanic that you need to move the mouse to shoot, it really fits the story. It is quite simple but addictive. Some smaller things which you might want to improve:
- Hiding the mouse cursor would make the feeling of controlling a bit better.
- Somehow the fullscreen mode did not work properly for me. Have a look at the "scale" property of phaser in the game config. This is what I usually use and works very good:
scale: {
mode: Phaser.Scale.FIT,
autoCenter: Phaser.Scale.CENTER_BOTH
},
Had fun playing this. Well done.
