As you progress in stages your task gets much more difficult. Small orbs will start to appear around the large one and you have to avoid/shoot them as well. More devious foes eventually appear that home in on your location with frightening speed. Fortunately there is help in the form of a missile power-up that floats by at random. Shoot it to upgrade your weapon temporarily and knock the enemies off the screen.
Analysis: Just like Red, Orange is an extremely simple and beautiful game. The Japanese theme adds an extra layer of elegance and is quite fitting with the sumo wrestling-inspired mechanics. Orange seems to be free of some of the glitches that plagued its predecessor, but unfortunately some of the novelty wears off after a few levels. The difficulty ramps up fairly quickly and makes the game feel more like an action-based shooter than the atmospheric game it starts off as. Without more objects to contend with, however, the game would feel a bit too empty. It's a well-chosen and necessary trade-off. Nevertheless, Orange is a stunning game to experience and a treat to play.
Cheers to Phil for sending this one in!
