Still trying to figure that out too. Some are worth more than others. If you start groot near, or at, the end of a lvl 1 mode. Then you can have the lvl 2 running during groot. Or orb. Might be a way to pick up some gravy points during multiball. But it might be better to use the multiball modes earlier in the lvl 1 modes to help complete them. Thereby getting to Cherry Bomb quicker, where there are some good points to be had. So far, the lvl 2 modes don't seem worth playing on their own. Better to start a new mode. It would be cool if there was a jackpot at the end of each one to reward finishing it. They are cool modes though. I love "unlocking" more of the movie when a lvl 2 starts.
I haven't gotten on of those big orb jackpots people have posted about. I might have to take the glass off and learn that mode better. I'm sure getting the right multipliers going is key.
There's definitely more thought and strategy now with this update.
I've seen a bug with Quills Quest. Sometimes it ends when only one ball drains and there's time left on the clock.
I'd really like to see progress indicators on the multiball modes. I've only completed them a few times.
This games has gotten addictive for me, hooray!
