Quite entertaining. A runner style game. I had fun finishing the first loop.

Good ol' Moon Patrol. Not an overly complicated game, but a safe, easy-to-understand title from an era where arcade games were still figuring themselves out. Good for a quick run through, timing jumps and shooting out obstacles. I guess the first ever full implementation of parallax, which is pretty cool. Not much else to it, but that's all okay. Good stuff.
The great thing about this game is how it builds the challenge as you play. On the first run it gradually introduces new enemies and obstacles that never feel unfair, but constantly force you to use your limited set of movement and shooting to contend with them. Once you run through the stages once, the challenge mode adds a few more variables on the first run before getting progressively tougher. There's also some neat graphical touches like how your vehicle drives through explosions from the saucer bombs when you just barely avoid them. The backgrounds do a good job of being unobtrusive while providing a good sense of traversal, but I do wish there was more here than just the tiles of the city and barren landscape.
A fun diversion that requires good timing but little else, it's a historical marvel that's aged perfectly fine, but is incredibly short-lived due to just how many modernizations of its gameplay have been made over the decades.
