1. Try to move to another lane when you see that the lane below you turns orange, not when the barrier is approaching, as this gives you more time to manuever in other lanes

2. Try to stick to 2 lanes that you move between. It is easier to predict and move accordingly. With the Blue Barriers forcing you to move into a lane, do it, but then still mark two lanes for yourself after you have moved past the Blue Barrier.

3. Once you have unlocked enemies and are facing them, still try to stick between 2 lanes, and spam Enter or E, whichever button you have it preset to.

I have found this to help me quite a bit so far.
