Extra features

Visual style looks good. I used a sprite shape for most of the levels to create a consistent feel to the game.
Turbo doubles the ball speed for 1.5 seconds.
Ball gives a puff of particles when shot.
A trail renderer follows the ball and changes green when turbo is activated.
Bloom added to all stages and a vignette added to level 3.
Sound activates when the ball is released.
Background music runs throughout the game playtime, without stopping or restarting.

UI

Title screen contains the game name, a start button and buttons to choose level.
Scorecard is located at the top of each level screen, containing the total number of shots on the left, the hole number in the middle and the current number of shot for the level on the right.
At the start of each level, a text will show for approx 3 seconds, stating which level it is, a brief description and the Par for the level. All of this is animated with a fade in, fade out effect.
When the ball is sunk, another message will show displaying for approx 1.5 seconds the score in golf terms and a random message from an array of messages. This text is animated with a fade in, fade out effect.

Levels

Level 1

Default level. Nothing special.

Level 2

Black holes will try to suck in the ball towards the centre. These have been animated with a particle effect.

Level 3

This stage has been created using a tilemap. In addition to this, the camera follows the ball with some "look-ahead" added and a vignette for more of a maze feel.

Level 4

Breakable door changes colour as it is hit. After three hits it disappears.

Level 5

Each of the checkpoints must be hit to open the door. Each checkpoint changes colour when hit.

Level 6

A tripwire opens the door, however the ball cannot trigger it. The tripwire changes colour when activated. You must hit the objects in the level into the trip wire. Hint, you'll probably need more than one.

Level 7

The ball sticks to the walls and floor. 

Level 8

The turret aims at the ball, and when the ball gets close it fires a missile at the ball. One every second. Missiles seek the ball when fired and rotate in proportion to where they're aiming. Also added a particle effect behind the missiles.

Level 9

Added effector to prevent passage through the tunnel, and particle effect to show the direction. If you can find the button, both will change direction making easy access to the hole.

Level 10

Rope bridges must be navigated through to the hole.
