Hello world. I'm Rokon, first ever Story Mode runner, and I just wanted to share a couple things I noticed that aren't immediately obvious.

• Change Bubbles (all kinds) cycle through all available colours in the level in a fixed order. If you're watching closely, you can always predict when to pop or drop one for best results. This applies to all modes. The complete cycle is Pink Green Blue Orange Purple Yellow, as displayed below.
• Similarly, Blasters always rotate counterclockwise.
• When you hit a Change Bubble, it will clear a group that it completes even if it is not the same colour as your thrown bubble. This is especially helpful in levels with solid blocks of Change Bubbles, as hitting three or more at once will always clear all of them.
• Paint and Paint Line Bubbles (including Change bubbles) will only clear if they are the same colour as the thrown bubble, and any bubbles changed by it will not be cleared along with bubbles of their original colour. If the thrown bubble has its colour changed, it will not clear any bubbles.
• Unlike in other games in the series, a thrown Star Bubble will clear every colour it hits, not just one.
• Thrown Special Bubbles will not wake Barons. Thank god.
