SunFlower: Chosen Apple Idea

I have decided to develop my Flower game idea. I decided to change the control system where you control the sun directly with your thumb, to a pivot system because the sun is above the flower, which would mean the players hand/thumb would cover a lot of the screen. I still wanted the player to have control, so I decided to have a sun at the bottom of the screen which you would control with your thumb. How this smaller sun moves, would reflect on the main sun which the flower would follow.
The height of your flower,aka your score, would be shown in the top right, above your health bar, which shows how much longer your flower can grow.

I have also decided to add something the player has to collect to keep moving, such as water or plant food which will fill up the health bar.

The petals on your flower would reflect its health and how many lives you have left. A full flower would mean 3 lives, a few missing petals would mean 2 lives, and 3 or 4 petals would mean you only have one life left. Having the flower show the lives would mean less to cluter up the screen
