Not a lot of work done yet today, I'll probably do more later. But, for now, I've added a spawner for my space junk, given it similar object pooling as I did to the projectiles. So now when the space junk collides with anything it disappears. There's more I want to add, like an explosion, loot drop, score, etc. Those will come in time. I do need to add some sort of sound effects too. Maybe that'll be my next task to tackle, adding sound.

Edit: As expected, I have gone and done a little more. I added a saved variable for the player's score and added a function to increment that when the space junk is "destroyed". I still need to modify it so that the score only goes up if the junk is actually destroyed by the player and not some other collision.
