Eliminate all bots with a single bullet, avoid the lasers, reach the exit, complete the eleven levels.

Thanks for playing :)

Notes:
- Only tested on recent Chrome, Firefox (slow) and Safari, not enough time for IE or Opera, sorry.
- Rendering code is a bit slow, a very recent browser may help.
- I forgot to preload the assets, it's less than 500k but give it a few seconds if you have a slow connection.
- You can refresh or close the window and come back later, the game will remember your progression.
- Find the Bieber !

- Added missing polyfills, it now works in Opera but still very slow, like Firefox.
