It's too generic; I've seen many games like this one. The timer is a bit annoying and stressful (this is even pointed out in the comments on itch). It turns what could be a relaxing game into a precision, fast-reaction game about... seeds and sunflowers.

I'm also not a fan of skill trees that aren't actually trees, but more like straight lines that unlock things as you go. They give you a false sense of strategy that isn't really there, because you can't actually strategize (for example, ignoring everything and upgrading only radius first). The game basically holds your hand and gives you the upgrades it wants you to have. I don't really see the point of that unless it's made for kids.
