<<12/17>> I get an error when attempting to assign a negative number to a variable, such as let a = -1.  It occurs even after declaring the variable and then later attempting to assign a negative number to that variable.

I just had a thought, how about this code?

```10 let a = 11
20 a = a * -1
30 println a```

I'll go test it.

Bonk!  Even a = a * (-1) gives a "Bad token 4 at line 20" BASIC error".

The way I have found to get around this is, if I want to assign -11 to the variable a I use a for loop.

While typing that code onto the Badge I came up with a faster idea.

It was:

```10 let a = 0
20 for i = 0 to 10
30 a = a - 1
40 next i
50 println a```

It should be:

```10 let a = 0
20 a = a -11
30 println a```

Such an easy thing to overlook when I was making it harder than it has to be.

I guess I'll have to learn to use GitHub so I can have the code readily available.

The 'game' I made previously to this one has two dots randomly wandering around the screen.  The dots are different colors.  The dot that lands on a space that is occupied by the other dot is declared as the winner.  It is a non participatory game, but you can watch it.  Out of coding that game came the idea of the space shooter.  I worked on three or four iterations of the HUD before I decided that the current one is the one I like.  It sits in the center of the screen and looks like:

Well, something like that.
