Really rockin premise, and lots of little effects really make this game stand out! I really appreciate the inclusion of the little "tips" on the side, although some cases were a little ambiguous still (are the small flowers withered? etc.) The minigames were a solid addition as well, I can tell you worked quite hard to get those just right.
I ran into a repeated issue where for some reason, despite doing the "correct" thing with the plant, I would be rewarded so little money that I end up losing the wave regardless. It was also a bit frustrating how the timings between the events were really sluggish, I felt like there was a lot of time pressure but I spent most of my time just waiting for animations to play out. A few tweaks to make the game "snappier" to reward faster decisions would be great.
Also, having to do a full reset (including tutorial) after a failure is a bit of a slog. But the game was fun enough that I powered through and did a few runs regardless. Impressive work!
