More Minor Updates (Happy Halloween!)

• Updated plasma weapon to consistently split into an up and a down projectile. It had been random, but it wasn't as fun to play. Now you can be sure you'll have a projectile going up and down when your plasma shot splits.
• Updated the Moose Rat Level 2 mid-boss yet again. I ran into the same problem I thought I had fixed where the monster runs off the screen. After my latest efforts, I was unable to recreate the issue. This one haunts me, so I don't want to say it's fixed for good. Keep an eye out.
• Modified many screens on the final level to offer more opportunities to change elevation.
• Many other small updates to improve the experience.
• Has anybody actually played all the way to the end?

Happy Halloween!
