This is an impressive game. The visuals all look nice and refined, and the music is pretty boppin. Even the sfx fit so nicely they sometimes feel like they're part of the music haha.
This game got pretty frantic in a good way. I found myself actually using some tactics figuring out where to go, how to prioritize killing vs healing plants, deciding whether an enemy was worth the trip, and so-on.
Performance was also great. A few of the other web submissions lagged on my browser, but this one was very optimized. As a bonus, the game was also very clear to understand, both from very simple instructions and very intuitive design. I think this was a very good and surprisingly high quality submission overall.
If I could give one piece of feedback, it would be for there to be more mechanical variety. The orange enemies didn't seem to add to much or change how I played. In fact, because they disappeared so fast, I ended up ignoring them until they were close enough that it would be convenient to kill them, and that worked out pretty well. I think one level (possibly the first that asks for 25 kills) also had a flower pot I couldn't reach at the top right, so I wasn't able to heal it.
