Whoops, had this comment typed in a tab 3 days ago but didn't hit send xD
Thought it was too easy initially, then got insanely hard by the end, then I figured out to cut flowers in the green box to slow the spread in the red box and managed to finish. It's a cool curve and I like that you have to learn how it works and figure out a "counter."
Would be interesting to have a game with multiple similar levels but with different rules, where you have to figure it out like that each time.
