An experience for the eyes, I would say. This game isn't about growing your flowers, or watering your garden, or shrinking in size, it's a peaceful artistic expression. For suggestions, I would make many different variations for branch variations. The gameplay is of opening the sakura buds and watching their petals scatter out. Adding a button that helps to generate a new sakura tree would be engaging for the people who want to click more, and the relaxed crowd can find a tree they like and just enjoy that one. Good game, can't wait to see more!
