So I finally got a UFO in Ten Pest. Next step was having something happen when you shoot it. Got it to make a noise upon laser impact and generating a new one on the screen. The controls are a bit hard to control, so I think that is the next step. I had a hard time lining up the shot to shoot the UFO. I think if I slow down the rocket it would be easier to line up shots for the UFO. Here's stuff left to do:

+ Design nine more UFOs and stick them in there.
+ Work on some UFOs that shoot.
+ Move UFOs up or down.
+ Make UFOs faster as game progresses.

If anyone would like to design a maximum-size 8x8 pixel UFO for the game, I'd be happy. What I plan to do is have the UFOs slowly move towards the rocket, like in Tempest. So in the end, what I hope to accomplish is a one-screen shmup in space, like Space Invaders. I have already set the maximum score to be 999,900. It's really just 9,999. I added 2 zeros at the end. You get 100 points per UFO shot. So you'd have to shoot 9,999 UFOs to get the maximum score allowed. And hopefully all this stuff I plan to do will fit in 32k.
