A classic of the arcades taken to outer space to rescue earthling princesses. That's Space Cropper 2, with spacial enemies and a skill challenge. As fast as possible and always watching for enemies and their missiles that may come across the spaceship, draw lines that cut off the surrounded area to both eliminate targets and save ladies in danger at the same time. That's possible moving with the Arrow keys and making use of the Space-bar to activate the cropping weapon. Watch out for the vulnerability that is consequence of this strategy and return home after concluding the mission successfully.
