Picoa race

This is a demake of Midway's only vector scan arcade game 'Omega race'.

Bounce around the arena and destroy all droids.

Since the original game had a spinner to rotate the ship, I added mouse control mode to rotate and aim as fast as spinner.

Due to resolution and cpu limitation the number of droids and mines are limited to 10 and 6.
