I got better at this game once I got the hang of it. However, I felt that the green shots have too much random deviation, and so around 50% of them would not even go close to target. Thus, I found myself spamming the green shots all the time, instead of calculating my shots and trying to move the inner + outer shields to bounce the green dots into the shield.
Interesting concept!
