Not much to do...

While progressing through the game and unlocking new levels, there's not much of a reason to go back to previous blocks that you've unlocked. they don't have any abilities either, like in the old pvz3. I think if breakout battles returned and appeared on previous areas there would be more of an incentive to go back and look at the town you've built (they wouldn't give taco tickets). On top of that, if you're stuck on a hard level and don't have enough coins for power ups, you could look for more breakout battles to save up. I just wish there were more ways to play the game instead of just the main campaign and vasebreaker, which is way too easy.
