I found a tiny bug, if you defeat the boss while on 0 health, it will still continue to the next one until you get hit again, then, with no sound of being hit, it goes to the regular ship destroyed screen. Other than that, cool game.
Thanks so much for enjoy my game. It's 6 hearts shown but actually you have 7 lives (7 times to get hit) before the destroyed screen. I didn't make a delay before LoadScreen command so there's no death sound.
