Cavern Crawl vs Astro Defender

Welcome to Cavern Crawl! Fly a spaceship through a cavern! Avoid obstacles! Avoid enemies! Shoot at the enemies! Collect orbs to gain points! Try to get the high score! Instructions: The ship floats down. Pressing on the screen will make the ship fly up. Your ship will also drain gas, so make sure to fuel up! Pressing the red shoot button will shoot a rocket. You can try to avoid enemies, or shoot at them, but be careful, the rockets will also destroy the orbs. You don't want to shoot the red or yellow ones since they will give you more gas. Collect red orbs to gain a point, but watch out for the purple orbs, they will subtract a point. If you get a yellow orb, you will get 10 points. Red and yellow orbs will also replenish your gas supply. Shooting the enemies will also give you a point. If you collect the orange coin, you will become invincible from enemies for 10 seconds.
