Air Gallet (older, Taiwan)

When you start a new game, you'll immediately be dropped into the first of six stages. Your fighter jet automatically scrolls upward, so your only job is to dodge enemy fire and shoot down anything that moves. The core loop is simple: destroy waves of ground and air targets, grab weapon power-ups that float in from destroyed enemies, and survive long enough to face the stage boss.

The game uses a traditional power-up system: you start with a basic pea shooter, but collecting lettered icons will upgrade your main gun or give you a secondary weapon like homing missiles or a spread shot. Watch your life bar carefully; every hit reduces it, and you only have a limited number of continues. There's no saving, so plan on playing through in one sitting. The menus are in English for the main options, so navigation isn't a problem.
