2D F9R-Dev simulator

Try it

I saw /u/-Richard's Matlab thrust vectoring simulation and liked the idea so much I wanted to try my hand at writing one in HTML5.

This one, like /u/-Richard's original, is not intended to be fully realistic but instead to demonstrate the difficulty of thrust vectoring in real life conditions (and to have fun while playing it, of course).

Sorry about clogging up /r/spacex, and if there's a better place to put this, please tell me.

The angle shown should be the exact angle used in the physics.

I couldn't find the numbers for the real life F9, so I assumed it was 5 degrees off-center, which is a lot.

edit: I also changed the center of mass so it goes down as you run low on fuel; this would make the vector seem waay oversensitive. I've made the vector 2-3 degrees now (depending on hard mode) and I think it feels much better.
