敵を撃ち、船を改善するためのアイテムを手に入れましょう。
You control a ship that can shoot enemies and you get items to improve it along the way. In order to advance in the game, you need to survive the waves of enemies by destroying them, or avoiding them. The game will end if the ship loses all its lives, otherwise will run indefinitely and will increase the score based on time passed, enemies destroyed, and items picked up.
