This was quite a pleasant, and very much challenging game! It's very interesting having to balance the risk and reward of trying to balance many plants at once while evading many bullets coming at you. The game also has a very nice mood to it with the comf music!

I think you should capitalise more on the risk and reward aspect by having a score system where possible, giving more bonus score by finishing quickly, so that players will leverage more on trying to plant many seeds at once.
