Game description:

R-THETA is an original, innovative, and retrostyled arcade game where you must fire shots from a spinning radar-scope line, trying to destroy enemies before the radar-scope line hits them. This game is based entirely in polar coordinates, which means that each point, instead of being based on an x-y grid, has a radius and a theta value, marking the distance from the centre, and the angle the point makes with the centre.
