TODO:
* 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 only allow hold for as long as collected energy from collectibels allows? Show a draining meter live when player holds.
* I often accidently press play again on game over, so maybe make an extra screen before gameover is shown.
* Collectibles and a shop (but a shop for what?) Lives?
* Implement the seeker type enemy.
* Slower movement at start, then it increases as game progresses.
* Figure out why stuff shows up in the center on start?
* Center items better on orbits, or get better orbit graphics (by manual upload perhaps?)
* Sound & Music.
* Make sure orbits don't have too many obstacles.
* Maybe skip player and obstacle updating while scaling?
* Current min and max speeds of obstacles should be closer to each other.
* Rotate orbits with obstacles statically distributed on them instead of calculating obstacle positions (for performance).
* 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?
