Translated from Russian (sorry, my English is bad):
The game does a good job of smoothing over the flaw of the original pvz, where after building up the plants there was nothing to do – here you're constantly busy either spinning the box, rebuilding soldiers (a unit in the game), inflating balloons, etc. The enemies are also varied. And of course, the game is very pleasant stylistically; the horror elements blend well with the leisurely pace of the original pvz.
In short, it's a great game, all the best to the developers :)
