Colony 7: Particle Storm

Hi there!

Another small step is done, I'm just done smoothing out the particle code.

The attached demo shows 6 particles at once on the screen.

Note: Only 4 of them make it down to the bottom. 2 of them are reserved for the players shots, so there's no need to display 3 particles below the cannons.

There's also occasionally a barely noticable tearing effect on particles on the left edge. But I think it's ok like it is.

I'm currently thinking about a tradeoff, but I'm not sure if it'd be a good one:

I could save one page of ROM plus 6 bytes of RAM, if I'd do the crosshair with the engine, instead of using the second sprite for it.

The negative aspect though: Since one is supposed to chase the enemy sprites, one'd constantly move it into a flicker situation. Even worse, when you shoot at an enemy, you have crosshair+enemy+shot alternating each scanline.

Well, I think until I really need the RAM, I'll just leave it how it is
