Unity 2D Game Project

I need help finishing my game called "ColorBounce" in Unity 2D. It is more of a simple arcade game where the user will click to spin a shape, in order to match the color of the ball with the same color panel. Here is a list of things that I need: 1) Add trail to the ball to see direction better 2) Add a slight angle to bounces that are head-on, so ball does not bounce back and forth. Basically, If the ball hits at X angle, then bounce it at X angle 4) Add PowerUps: Double Points, Triple Points (Will be in Arcade Mode). If ball hits a certain panel (maybe black panel), then the player will get either double or triple points. Can implement any way you want. 5) Make modes - Arcade Mode, Regular Play. Arcade Mode will contain PowerUps and User can choose which shape to play with out of 3. There should be three shapes: square and the two shapes that are already in the project. There should be a timer of 1 minute and player should get as many points as they can. The regular mode will have 3 levels. Each level will have a different shape. The shape with the lowest amount of sides will be the lower level. You have to reach a certain amount of points to get to the next level. If you hit a bad color, instead of dying you will lose a point. There should also be a certain level of points that unlocks Arcade mode. Player cannot play arcade mode without playing regular mode. 6) I will need all of the things in different scenes incorporated into game as well. It will make sense once the project is opened. What I have provided: Right now there are two shapes in the game (in different scenes). I will need a third shape made like a square. There is functionality for a regular play mode that contains one shape, high score, etc. There is also basic menu selection. There is one a PowerUps of the ball changing colors in a different scene.
