I would have loved to see some extra elements in the levels to add more restrictions to how the flowers can be placed. The mechanics as they are don't really lead me to feel like I am solving a puzzle, but more like just "making it work".
I do like the idea here, though. Not sure how many stages there are (it joked about 100, but I stopped after finishing level 30). It is satisfying to see everything blow up. The sounds are nice. The music is nice, but it does get a bit repetitive after a few minutes. When you fail a puzzle, I'd love to be able to see how I messed up (perhaps some kind of ghost flowers left behind so I can understand what I did wrong). Overall a fun entry with a lot of potential to expand into an interesting puzzle-y game.
