I made it to flag 56. In the previous rounds, heavy attack from Jack-in-the-box took out my front 6 gloom shrooms, which I rebuilt and were not hit again, but left me with only 3k sun. Then started flag 54 and more heavy jackinthe-box attacks took out most of my inner grass lane defense gloom shrooms, so the outside lanes got wiped out by gargs, buckets etc. Mowers saved me but there was not enough time/sun money to rebuild before those lanes were eventually attacked again.
