Soo, This was my first time participating and working with javascript/phaser aaand.. well I kinda ran out of time
I can't call this finished, buuut there is a boss (tip: it's below and slightly to the right of the upgrade ship)

It also doesn't seem to work on IE

Controlls:
arrow keys for movement
spacebar to fire your rockets

Tools used:
Framework: Phaser (http://phaser.io)
IDE: Webstorm
Art: Paint.net, Photoshop (for transitions cause I was lazy)

Known bugs:
The boss wanders off - it may even walk out of the level if you give it enough time, it even enjoys to go for a fly from time to time.
Generally mob ai is.. really simple
Monster health bars are slightly glitchy


..the great jellyfish watches all..
