R-Theta 2

R-Theta 2 is a game based in polar coordinates. Every point in the game is assigned a radius and theta value, denoting the distance of the point from the centre, as well as the angle it makes with the x-axis.

The player is in control of a triangular shooter, built into a constantly rotating radar-scope which must be protected from collision with other enemies. Use the up and down arrow keys to decrease or increase the ship's radius from the centre. Hold the X key for rapid fire, tap the Z key to shoot and use the C key to launch a destructive missile.
