I have been in a big retro big the past few years and one of the games I played a lot on the Intellivision was Shark! Shark!.

Feeding Frenzy is basically Shark! Shark! with stages. You are a fish that eats smaller fish, eventually you grow in size allowing you to eat bigger fish. Each stage has a feeding bar you have to fill to beat it. As you progress levels get jellyfish, golden fish, mines, poison fish, giant fast fish to add a little challenge.

The main game took me a little over an hour to beat. Beating that unlocks a time attack mode.

I enjoyed playing Feeding Frenzy and plan on checking out its sequel.
