Tasty Planet - Back for Seconds is a fun arcade game where your goal is to guide your character, a grey goo, to eating anything smaller than itself from the board. In the mean time, you also need to avoid collision with bigger elements than your goo, or else it'll get smaller.
The more your goo eats, the larger it becomes and the faster you complete each level. A good thing about playing this entertaining game is that it automatically saves your progress (if you exit the app and launch it again, you can continue playing where you left off).
You get to choose from two types of gameplay: Timed and Casual. If you don't wish to be pressed by time and just relax playing this game's exciting levels, you should try the Casual mode; this way you can take your time expanding your goo and enjoy the beautiful background music.
An advantage of playing this game is that, after you complete the offered levels, you get access to a collection of bonus challenges.
To summarize, if you're looking for an entertaining arcade game, you should try Tasty Planet - Back for Seconds. This application provides you with dozens of challenges, automatically saves your game progress, and its price is reasonable.
