Mars

You control a small spacecraft moving horizontally across the top of the screen. Your job is to bomb the cityscape below before it can shoot you down. You press the spacebar to release bombs, each one falling in a straight line. The buildings fire missiles up at you, so you have to keep moving, dodging their fire while timing your own drops. The pace is constant, and missing a shot means waiting for your next bomb to be ready. It feels like a tense, methodical dance between attack and evasion.
