It is mobile-friendly to play on PC; it is WASD format and space to shoot, and on mobile, wherever your finger is, that's where it will shoot and go. there is a knockback when you shoot.. There is a GOD MODE at a specific score where the knockback is removed, and you get lifesteal. DEMOLESH THE ASTEROIDS. Yes, I KNOW the spelling of demolish is wrong, but I DID IT ON PURPOSE because it looks cool. The mobile controls are very tough to make because Scratch doesn't support dual touch. That's why, for the mobile player, it might be hard to play. fine, you deserve it You get god mode at the score 500:D
