I really like the art style! The title drew me in, so great job with the art! The gameplay was a little confusing, here is what I noticed:
1) there were no indicators of what tiles I was targeting, so I was never sure of which tile I would place a flower down into
2) I didnt realize until my 3rd /4th playthrough that there was only one type of plant, it was just growing somehow - I think if it was placed next to water
3) The visual indicators of when the plants were about to wilt and disappear were to subtle, it was hard to tell which ones I should prioritize.
A lot of solid mechanics and ideas went into this game, so good job!
