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 pvz...
Hey @yegsten , thanks for the feedback. It's true that adding new ways of playing could make the game more interesting, we'll pass along your comments to the teams.
It's also good to keep in mind that this version of the game is a soft launch and is only available in a few countries, so it's possible that the game gets tweaked a bit when it's fully available. I guess we shall see in the future 🙂
