/* 
TODOS:
======
- Determine game over conditions
* Time based per palette (based on number of colors in it)?
* Number of misclicks?
- Write instructions on game start.
- Game gets visually exhausting after some time. Maybe there should be a status screen once in a while, just to break it up?
- Maybe, once a color has been clicked/tapped, stars should stop spawning in that color for remainder of the level?
- Maybe show the name of each palette used?
- Maybe show game title on top, above score?
- Brainstorm for game title: color space, colorful space, colorful universe, luniverse, loonyverse, star catcher, 
planet catcher, sort the universe, planet sorting, Lala Universe, universal palettes, Colorvoid, Color Void, 
Beauty-verse, Space Splatter, Basket Case Balls, Everything is Round, What Goes Around, Unruly Universe
- Particle effect when a star is clicked?
