Well Im torn on whether to recommend this game or not. It only takes 2 hours or so to complete the main game and unlock all the acheviements. So I would not recommend spending much on the game.
It is however, fairly interesting to play. There are two modes. "Cliassic" mode which I didnt like as its a simple clickfest as you franticly click to gather resources to continue building your plant. Then there is a "strategy" mode, which is esentially a turn based game. I enjoyed this mode much more. In this mode you plan each turn and spend your available resources all while trying to grow your plant enough to produce seeds to gain points to spend on new plants and upgrades.
Overall I do recommend this game, just know it will only take a couple hours to complete and try to grab it at a discount like I did.
