nice idea but that's it, player needs multiple units to stand against group of cops since plants don't withstand much damage, plants can (and need to) be upgraded but that requires time and resources and player lacks both, 1st mission is easy but 2nd isn't since getting plan´ts requires time and resources and often for some reason player can't create multiple plants even if has resources, "opponent" can create múltiple units easily, can't send multiple plants at the same time´to attack so its 1 plant at a time against 6 cops so outcome is expected, too small screen makes sending plants to where they are needed difficult and due player can move 1 unit at a time it again leads 1 vs many, ok but too tiny graphics and ok sounds.

overall bad game due multiple reasons like time required to get plants or upgrade those and plants not withstanding damage much, ability to send multiple plants at a same time would help alot and same thing with bigger screen (atm copstation is 2 screens away from mother plant so when player sends plants to attack on it plants march 1 by 1 there and get destroyed).
