Works fine here.
I've just added a fuel guage that changes colour as you get lower on fuel, and when it's out, that's it. No more thrusting for you!
I've also added a blue button on the screen that you can click to randomise the terrain, reposition the lander and refill the fuel tank.

It's not perfect, as if you're thrusting when you run out of fuel, then the particles are still created. Also, the code could be split up into functions to make it more reusable, but it was a 5 minute hack job when the boss wasn't looking
