Like others said, don't buy this unless you are into gardening and education of plants. I would not recommend it unless it's on super sale and you actually think you might be interested in gardening/plants which is why I got it.
Learn about plants and if you like gardening you'll probably have a bit of fun
Strategy mode is fun and relieves the stress of clicking like crazy to harvest everything
Very short: I unlocked and beat everything in less than 2 hours, needs more content... There's no reason why there should not have been more plants added... Fruits, veggies, more flowers, more everything should have been added from the start.
Very repetetive. Every level feels identical.
Overall I give it about a 5 out of 10.
sound: 8, the music is actually decent
content: 2: needs a lot more content
controls: 5: Classic mode is a clickfest, but strategy mode allows more time for thinking things through. The UI is ok, nothing special
