As things stand in this current version of the game, as the player, you can fly around, shoot asteroids and pick up Zank bits. Colliding with asteroids busts your ship into tiny pieces and you only get to see the pretty particles 3 times before being kicked to the Game Over screen. If you manage to dodge all the asteroids and make it past the bounds of the view, you find yourself in a new zone with a whole new, albeit exactly identical, set of asteroids to collide with or mine. There is a score, of a kind. As you destroy asteroids and collect the bits of Zank, that 'score' increases. I have a purpose for those points. 

The next update will see the introduction of most of the major features I had planned. Sometimes, when you slip past the edge of your current view, you'll come face to face with a pirate.  Or even a whole pack of pirates. And they want your precious Zank. Because in Zank (the game), Zank (the points) are your currency. They are how you'll purchase upgrades like a beam laser, scatter gun, rail gun, missile launcher, or a mine layer. You'll use it to buy extra lives. You'll use Zank to make your ship faster or more agile. You'll spend that Zank at space stations that can also be randomly found throughout space. 

Following the aforementioned update, I'll see about making those play spaces persistent so you can revisit stations you've found previously. 

I don't know if there are any other Asteroids clones that will have nearly the amount of features I have planned and it's probably going to take me quite a while to get all of this stuff working but I know that I'm going to stick with it until the end. I can see this whole game, I'm playing it in my head right now. Eventually, you'll be able to play it too. I can't wait!
