Been a while since I whipped up a MicroBit game.

This one starts easy and gets harder.
* Your "ship" is on the bottom at the center to start.
* Every time you press A+B you cross to the other side. *You can shift the ship left/right with A/B buttons.
*It starts with one Asteroid bouncing back and forth on a random path and adds another (up to 6) every time you cross.
