I love the art, everything looks so good including the tooltips which were a great touch. I noticed a couple bugs, 1) When I pressed R at one point it changed the state of the game to something I think is unintended, and 2) When you go to water the second symbol if there's already plants there, you have to cut them and wait for new ones to grow in the same place before they'll turn purple.
Also if you've cut one of the plants in the symbol but watered others, it looks like a plant will never grow back in that spot so you can't progress :/ Otherwise one of the most polished games I've seen yet, great job!
