After about a year of the Gaming App of the Week, I've been very hard on games that are nakedly derivative of existing hits. Then one comes along and literally does everything a previous success did, except upside down, and I feel like I have to tip my hat. That's Sea Stars.
This game is an inverted Jetpack Joyride. Halfbrick's hit from the summer had you flying an endless route through a cartoon research lab, avoiding hazards by tapping the screen to elevate, In Sea Stars, by Hothead Games, you're a dolphin making an endless run through the ocean, tapping the screen to dive. Tap, hold, and release, and your dolphin will plunge to the bottom of the screen, then shoot to the surface and jump. Jellyfish are the fatal obstacles, mimicking the electrical traps in Jetpack Joyride.
