One of gaming's earliest megaton hits. Even these days, it's not bad, if simple. Momentum on the meteors splitting up is actually a neat show of physics, since it's a fairly consistent defense to blast away a meteor coming at you. Wrap-around is a neat gimmick for this early into gaming, particularly since it impacts the player's shots as well as the player themselves. Hyperspace - a carry-over from Spacewar! - is rarely the best solution, so you mostly lean on it as a panic gamble. But it's cute that it exists, very much an element of early gaming that doesn't make sense to translate to modern conventions.
