TODO:
* Make some orbits with many evenly spread collectibles.
* Make particle tail jump when player jumps.
* What if holding mouse down didn't just stall movement, but move player the other way?
* Maybe rotate enemies a little bit every frame, back and forth, so that they seem more alive and less alike. (Looks a bit silly).
* Update the instructions to explain the new hold to stall mechanic.
* Maybe give player 3 lives.
* Implement the seeker type enemy.
* Figure out why stuff shows up in the center on start?
* Sound & Music.
* Maybe skip player and obstacle updating while scaling?
* Would also be cool to be able to jump in AND out of orbits, but hard to implement. Or maybe just tap on the orbit to go to?
