From the mid-game onwards, you'll need the skill to keep rotating continuously to survive

At first, you can calmly rotate things around. From the mid-game, you'll encounter situations where you need to keep about six items juggling across four slots to survive. At that point, while you can resend items after a 2-link or 3-link combo returns, it's easy to get stuck. The trick is to leave a small gap after a 2-link combo before sending out the next one.
