Two astronauts are in peril during a spacewalk mission on a space station. To turn the circular platform and help them dodge the spacecrafts flying by you touch the left screen to make it rotate clockwise and right side for counter-clockwise.
For every spaceship you let pass through the working area you get one point. As the traffic intensifies it will become more and more difficult to avoid disaster. If a spaceship collides with an astronaut, the game is over.
