Can you focus on one challenge, then replay the same level and focus on another and still have them all checked off?
YES. You can focus on one challenge, check it off, then replay the same chapter to focus on other challenges. All challenges are cumulative.
This also allows you to earn money and work on upgrades as well. So use all abilities of each character a lot.
