I struggled with this one.
The first goal was quickly achieved, but then the second platform was not reachable.
Also, it looked like the plan was executed automatically, i.e. I have to be fast to position myself on time?
I set the todo list this way: 0:00 shoot enemy, 0:30 invert controls, 1:00 shoot enemy, 2:00 shoot enemy. Then all you need to do is hit the shots, paying atention to the last enemy, because it has a shield.
