The art style and the idea of the game is really good. I loved the game since it was really a relaxing game and I could plan out what plants I should kill to get the upgrades. But I want to point out that I never killed any higher hp plants and I stuck with lower hp plants. When the growth completed plants are harvested, there isn't a consequence for it. Like I don't need to be bothered about it. Could have added a difficulty for it in my opinion.
Overall, a great game. Great Job!
