Updated scaling and mobile controls.

The most recent update to ASTEROIDS-ZENECA makes the game scale much better on mobile. The camera is more zoomed out so you can see more of what is happening in the game. It also runs in landscape instead of portrait now because it makes it a bit easier to hold onto it and use the controls in my opinion.  The controls are a bit bigger and they've been made partially transparent so they don't block so much of the game.

This entire game has been a fun experiment into the world of vector graphics. The visuals are basic, the gameplay is just there as a small stress reliever for myself and I hope it helps others as well. The on screen controls for mobile are simply HTML buttons stuck on top of the canvas. There is no framework or game engine involved.  This was done to be the simplest, fastest, quick and dirty game I could put together to try out vector art and I am overjoyed with the result. 

Mobile browser support wasn't even a goal when I started the game, but when I tested it on my phones I was surprised at how close to acceptable it was with zero work on my part.  That inspired me to put in the extra bit of work to get it supporting mobile a bit better.
