Planets

Planets are in.  You can land on them.  Land hard enough, and there will be an explosion and a HP penalty (though there is no penalty for losing all your HP).  Most planets have too much gravity to take off with normal thrust, but hold down S to charge up for a while, and when you hit W it will give you an extra boost to get out of the planet’s gravity well.
You can’t land on the stars.  You will, however, zip through them like nothing happened, leaving a trail of explosions.
The planet and star text data files can be modified to add more planets and stuff, and the basic player data is now loaded from a file too.
You’ll notice the current ship graphic is basically from Tyrian, it’s actually from here, so it’s free to use.  There’s quite a boatload of free-to-use pixel art in that; it’s too bad 90% of the ships are about five pixels wide, and therefore pretty much useless to me.
Similarly, the planet and star graphics are from NASA, which are also free for commercial use under certain restrictions which are easily met.
I think next up is some sort of emitter system to give the ship a fiery rocket trail and perhaps some smoke, maybe for projectiles too, and probably cleaning up the whole timer thing, which I now think that I made much more complicated than it needed to be.
