Orbit Toy Week 2 - Giving a task

Last week I made the orbit toy for week 1 of a game jam, in which I had to make a toy under the theme "Revolution" (https://surrealgaming.itch.io/orbit-toy). For this week, we had to give that toy a task under the theme "Rebound." So I have improved upon my original experience and now have a short little game that I made in a couple hours.

Controls this week are a little more complex to give more control.

 CONTROLS:

Left Mouse Click: Spawn last created planet

Right-Click + HOLD + DRAG: Create a planet and drag to the desired size, mass is proportional to radius for simplicity.
THEN Release Right-Mouse-Button to create the planet at desired size.
THEN MOVE MOUSE to position to give desired velocity and click on RIGHT-MOUSE-BUTTON!

Mouse Scroll Wheel: Zoom camera In or Out.
