I played your level, and your (I assume) first one as well. I actually quite enjoyed the second one (Spiny or Sky), it was simple yet satisfying which are my favorite kind of levels. I do not understand the low clear rate on your plant level, there was even a comment that stated that it was too random or something to that extent which I disagree with. I doubt he was a patient player as plants are not the most threatening enemy in Mario Maker by any stretch of the imagination. Regardless, your level, by virtue of being an actual level, is perhaps one of the best that I played. I must admit that the first one lacked what the second one had, but hey, my first level was a generic run to the finish stage.
