Vectors Race 2

RULES:

1. Your next vector's length depends on the current's length. Don't be too hasty or you'll crash.
2. If you touch the edge, your vector's length is reset to 0.
3. First one at the finish wins!

Game Modes:
- two players on one device,
- two players via Bluetooth.

This is the continuation of Vectors Race which had to be discontinued due to technical issues.

Thanks to Franciszek Stefanek for motivation.

Known bugs:

1. All fixed for now, let me know if you find anything.
