I added another enemy type in the game. Most of the time was spent trying to make its laser beam not overlap the enemy ship. When two characters overlap, it makes icky white garbage show up on the screen. Right now it's 2k, but I thought I would have to make it be 8k, but after looking at the code a bit, most of it is for the in-game part, so dividing the code wouldn't save very much room.

The new enemy is made of just one character and the other character is its laser beam. You cannot shoot its laser beam, but you can shoot at the ship. So you have to dodge its shot and shoot at it.
