Wow, very cool concept. The camera switching is a really cool feature. The tooltips at the top-left were a really nice touch as well. The day/night loop is a cool implementation of the theme, and the weapon variety is nice in combat mode. The short range gun was satisfying to use.
I do wish there was a bit more clarity with a few things. I didn't realize the white circle was the recharge station at first. And when watering I couldn't tell what plant I was targeting, it seemed inconsistent.
Very cool idea though, and pretty fun. Nice work!
