Did you say this game has programmable turrets?
Each weapon has 8 prioritisation options - turrets with good tracking speeds can be told to prioritise quicker targets, or those closest, others can be told to go for the stronger, or those furthest along the course. The full options are fastest/slower, strongest/weakest, furthest along/least far along, closest/furthest from turret.
An interesting mechanic of the game is as targets are damaged they change their speeds (either up or down, there's no pattern). Because of this, you can build batteries that prioritise faster targets, so the stream runs at a lower speed, allowing more time for damaging them. Unfortunately, this has the problem that some turrets just can't hit the fastest balls due to transit time of the bullets, so you really have to fine tune things.
We usually get the turrets at the start to go for the strongest targets so that a stream of weak balls is then available for those later on. We then set the EMP turrets, which slow down targets, to prioritise those fastest.
Later on in the game you can unlock rail gun like turrets. If you put these far along the track, looking backwards along a straight path, and get them to aim at the backmost target in the procession, they will damage all the targets infront, too. You really do end up using all the different settings.
Do the different color enemy balls have different strengths or just appeasing to the eyes?
They are of different strengths and have different speeds. 1 strength targets are always green and go a certain speed; 2 strength balls are blue and go a different speed (there's no real pattern). Blue ones, when shot, become green, for example. You learn to fear certain balls - the black one is fast as sin and is worth 10. You only have 100 'lives', so let 10 of those through and you're gone. Later on in the game some balls are worth over 100 when they spawn, but it's made so you can't lose more than 60 lives for each unique ball, and you regenerate 1 life per round, so you are allowed 1 'slip up' before you're punished harshly.
Some rounds you get lots of weaker targets, some you get a few incredibly strong ones (much harder), and your setup has to be able to cope with both, or you'll be in trouble.
