I loved the idea of this game and the take on the theme but the execution needs a lot of work. I never even got the tiniest sprout let alone a tall sunflower seed.
Level 1 is way too fast, even when I'd figured out I was basically playing snake, it was too fast. It took me over 20 attempts to complete the first level and then oh there's more of the same.
IMO the first level of any game should be easy, it should be almost impossible to fail the first level.
Also the seeds and rocks can spawn on top of each other
