The art is absolutely beautiful! This is a fun little cozy game and it feels wonderful.
Some criticism: First I don't understand why the world is so large, using up the first island already takes ages to plant and harvest, so why go over to other islands also because you can instantly replant on the harvested spots if you want to go that route, but this didn't take away from the game, I was just curious why you would use the very far away islands.
Also, having a "buy all" button next to each flower in the shop could be great, I spend ages in the shop clicking which may be by design, but the planting/harvesting is already the thing that slows you down so having that buying time on top could be improved upon. I can also see a situation where you then press buy all and then get in over your head with the amount of flower you now have to plant, which could be a good thing and maybe force you to use more space maybe, just an idea.
But great job on this game, I really, really liked it :)
