Bit strange how the main motive in the game seems to get a highscore, and yet when you end your game the fate of the world is supposedly lost. Is there an ending if you keep playing? If it is a finite game, it feels a bit monotone. Even for highscoring purposes, it takes a long while before it starts getting difficult (when the asteroids kick in), and by then it really gets difficult at once. I like the gameplay overall, but not so much the monotony of the journey. At first I thought it'd be a bit like Space Invaders, with a new foe for each level, but it turns out the same foes repeat over and over, stage after stage, occasionally introducing one new combatant to cycle through in the different stages. I think I'd like either longer stages and more intense battle, or a finite number of fewer stages, each one with its own challenge. It just takes too long to get anywhere, even if it's fun at first, and doesn't feel like a game you'd want to try multiple times to beat your highscore. That's just too time-consuming a task. Anyway, graphics, music, etc were great, gameplay is the part I feel's a bit lacking. Keep it going!
